INTRODUCTION.
1. CONTENTS.
This book is a revised edition of our Handbooks 20 and 21 , now combined
in a single volume.
2. FORMUL>C.
As the British Standard Specification for column stresses is now so widely
used, we have recalculated the safe-load tables, column bases, etc- in
accordance therewdth. Those who may prefer Fidler's formula will find
the safe stresses tabulated on page 95, and the corresponding safe loads
in previous handbooks (also in booklet C.619/B).
3. WELDING.
This chapter has been enlarged and rewritten to accord with current
practice.
Designers are rightly advised to " forget nonnal design " with their
new medium ; but should remember that it is far from economical to use
girders welded up from plates in substitution for plain rolled steel shapes.
The saving in weight thereby achieved may be altogether outweighed by the
costly workmanship involved.
4. BROAD FLANGE BEAMS. GREY PROCESS.
A concise statement of the uses and advantages of these sections will
be found on pages 7-13.
As may be seen from the list of sizes on pages 16-20, and the notes
thereto on page 21, the various sections are rolled in four standard weights
—known as the Die, Dil, Din, and DiR series— and can also be roUed
to intermediate weights, of which some tj-pical examples {marked i) are
included in the aforementioned list of sizes.
6. SPECIAL SECTIONS.
In addition to the foregoing, two special series are rolled at the
Differdange works ; —
(a) Seven sections, from 4' to 8', with extra wide flanges. speciaUy
designed for use u [x'!--. or mints. Their sizes and properties are tabulate^l
separately on pa^e 20 and elsewliere.
(b) Four sections, ti' .< 0', n' > H'. H)' X 10*. and 12' x 12", in
American w ' ■ ■,. Tlirir dimrnsiuii't and proptrti.-* are tabulated scpa.cately

Notes to Fourth Edition.
In order to bring this handbook more up to date, the chapters on Metal
Arc ^\ elding and Extras have been substantially altered and other minor
corrections made.
BRITISH STANDARD SPECIFICATION 449 {1937). Inder the War Emer-
gency Revision, still in force pending revision of this specification, the
following maximum working stresses are allowed.
Tt.-nsion and compression in beams, 10 tons per square inch {extreme fibre).
Wlu-re the compression flanjje of a beam is not supported laterallv, and the
unsujjpurted length exceeds 20 flange widths, the stress is reduced to U-4— 22L/B.
A beam whirh has its compression flange witliin the depth of a concrete
floor, or whicli receives sufhcient lateral support from the transverse members
may be regarded as laterally supported.
Grilhti^e Beams.— The working stress ma\- be increased by 20"; for tension
and compression flanges of beams. 50% for shear, bearing, and tension faxial)
stress, and 33^% for high tensile steel. B.S.S. 449. clause 11, is otherw-ise
unaltered.
FilUr fhor BcomK.—Jhe stress is increased from 9 to U tons per square inch
for mild steel and the stress calculated on the beams alone niav be increased to
1 1 -f t. provided that t (/) the concrete thickness above the top flange is not taken
as more than 3 inches.
Olher Encasrd Beams.— T\ie working stress is increased from 8 • 5 to 10 ■ G tons
per square inch.

BROAD FLANQE BEAMS, GREY PROCESS.
ORIGrN AND ADVANTAGES.
It was an lingli^hinan, Henry Grey, uho discovered a means of manufacturing
rolled steel beams with wide Hanges. The first works to install a Grey Mill was tlie
Differdangc Steelworks in Luxembourg, in IHOS ; two years later -i similar mill was
instiillcd at the licthlthcin works in the Lnjlcd States. So great u as the dvniand
for these widc-tlangtd bcanih that within a few years the Betlik-hem works duplicated
their plant ; and more recently several other foreign works have undertaken the
manufacture on a large scale of similar beams.
A description ol the Grey Mill and ol its important technical advantages over
the ordinary horizontal rolling milt will be found on pages 11-13,
These wide-llangcj sections now constitute a bubbtantial proportion of the steel-
work of every important building in the United States and on the Continent. For
example, in a 26-8torey bank building at Antwerp the steelwork consists almost
exclusively of Broad Flange Beams rr>lled at the Differdangc Works.
On the Swiss Federal Kailways, the poles and other structures supporting over-
head conductors are composed in nearly all cases of Broa<l Flange Beams ; and, of
350 railway brid^'cs built between 1918 and 1029, alnif^bt all are of Broad Flar
Beams embedded in concrete.
These Beams have alao been used by many British engineers of the highest
standing, and for a great variety of purposes, as may be seen from the liat of typical
users on page 10.
The fundamental advantages of wide-Hanged t>cams may be briefly stated as
iollows : —
AS COLUMNS. The smaller sections, ranging from i" x 4* to 12* x 12*.
all of e<iual height and width, are obviously idi-al columns. Even the best of the
British Standard Joi^its compare with them unfa\ourab]>'. Ihis point is demon-
strated graphically in Fig. 1 overleaf, where a comparison between B.R Beams
8' X 8' X 43-6 lb, and K S. Joists 9' x 7' X 50 lb. shows the latter to be iligbtly
weaker, although nearly 15% heavier than the B I\ Beam.
lU instead of the ft* X 8* section, we u^e a B.F. Beam 9|' x 9)^ rolled to its
new minimum weight of 41 lb. per foot, the comparison is still more advantageous to
the Broad Flange Ikam, showing a gain of 5% in capacity with a saving in weight of
18%.
When the comparison 1$ with built-up coiinrnts, viz., steel joists or channels with
plates riveted to the llanges, the economy and conxenirnce of the Broad Flange Beam
are still more obvious, as may be sc<mi Irom Fig. 2 overleaf.
In the United Stales, the columns in tall buildings arc almost invariably composed
of Broad Flange Beams. The fact that each section is now obtainable in a wide range
of weights adds greatly to their utility for this class of structure.

AS BEAMS. I-or use as beams or girders. Broad Flange Beams supplement
rather than supplant the ordinary- rolled steel joists. That is to say. the use of Broad
Hange Beams as honzontai members is chiefly where the span and load are beyond
the range of ordinar>- steel joists. In this connection, it will be observed that the largest
British Standard Joist. 24 x Tj* x 9i5 lb., has a section modulus of only 211 {cubic
incUes). whereas Broad Flange Beams are rolled with 12" flanges up to 40" 'deep civine
any required section modulus, without plating, up to 873 {cubic inches).
It follows that the utility of Broad Flange Beams as horizontal members must
be sought primarily in a comparison with the various t>-pes of buUi-up girders. As
may be s*en from tigs. 3 4, opposite, the plain rolled steel beam shows a great saving
m ^ceight and cost : and when the quantity required is at all considerable, a very
great saving in time also. ^
Accordingly. Broad Flange Beams of sections 24" x 12' to 40' X 12' have

OTH ER USES. The lighter sections of Broad Flange Beams have been
extensively employed as poles, etc-, supporting overhead cables in South Africa, India,
Switzerland and elsewhere. Their advantages for this purpose are explained on pages
154-164. In brief : tubular or latticed poles, though lighter, are considerably more
expensive, even in the first instance ; while the cost of maintenance is greatly reduced
bv the diminished liability to corrosion of the solid steel beam and the fact that it can
readily be repainted all over
Broad Flange Beams ha\e been extensively used in Hong Kong, Singapore and
elsewhere as piles — in some cases in rolled {i.e., unjointed) lengths of 100 feet and more.
GENERAL ADVANTAGES- Their relzXive f teed 07n /torn corrosion,^ and ease of
maintenance, are of course important advantages of solid rolled sttel beams in com-
parison with all types of riveted members. So also are the facilities which the wide
flanges, without taper, provide for sotind and simple co^ivections, whether welded or
riveted. The ahse^we of projeclt>fg rivet heads is often an important advantage, as in
beams or stanchions to which crane rails or shafting brackets are to be fixed, and in
designing bedplates for heavy niachitiery.
In short, Broad Flange Beams save time, money and weight in steel construction,
and greatly facilitate the task of the steelwork designer.
• These beams can be supplied, when desired, with a copper content, and m the higher tensiles
now cmplgycd for many purpo&cs. for further details, see **Tcsts/'

BROAD FLANGE BEAMS, GREY PROCESS.-Continued.
THE GREY MILL.
The Grey Process of rolling, as employed at Differdange, comprises three stages,
as follows : —
(a) The ingot is rolled in an ordinary Blooming Mill, into an ** H-shaped "
bloom, as shona in Fig. 1 on page 12,
(6) The bloom then passes to an Intermediate Mill consisting of two pairs of
rolls, shown in Fig. 2,
(c) The Finishing Mill, shown in Figs. 3 and 4, consists of two pairs of horizontal
rolls and one pair of vertical rolls, in two housings, placed as close together
as practicable-
The rolls shown in Fig. 3 bear on the edges of the fianges and determine the
flange mdth.
The horizontal and vertical rolls shown in Fig. 4. determine the depth and thickness
of the web, and the thickness of the flanges, respectively.
ADVANTAGES.
The advantages of this process are best realised by comparing with a horizontal mill
as used for rolling ordinary rolled steel joists. The finishing pass of such a mill is shown
in Fig. 6. The flanges are produced by the plastic metal being squeezed into grooves
in the rolls, through pressure exerted on the web.
The difference between the peripheral velocities of the rolls at the points where
they bear on the web and on the edges of the flanges respectively, is obviously considerable
in the case of a section with deep flanges, and results in the flanges being dragged through
the rolls.
Consequently, the quahty of the metal in the flanges tends to be inferior to that
of the web and there is a tendency to form fissures at the junction between the web
and the flanges.
In the Grey Mill, on the contrar\', both the flanges and the web are formed by
direct pressure ; the section is rolled aU over and the metal is squeezed together instead
of being dragged apart at the junctions between the Aveb and the flanges ; the superir.r
finish is ver^^ noticeable.
VARIATIONS IN WEIGHT.
In the ordinary horizontal rolling mill, the weight per foot of a section can be
increased to a limited extent by spacing the rolls in the manner shown in Fig. 7. It will
be obsen'ed that the web thickness and flange width are increased by the same amount.
It is not possible to separate the rolls in this way by more than l", as otherwise fins would
be formed.
In the Grey Mill, however, by suitably spacing the independent pairs of rolls shown
in Figs. 3 and 4, the section can be varied considerably, not only in web thickness and
flange width, but also in depth and flange thickness, as shown in Fig. 5.
The considerable limits within which the various sections can be varied in this way
may be seen from the Table of Sizes and Properties on pages 16-20,

THE GREY M ILL,— Continued-
In addition to the sizes there shown, each section caa be rolled to any desired
iiUermtdiatc weight. Observe, huu ever, that the ratio of u el> thick ncss to Hange thi(_kness
must be kept constant, for technical reasons. Thus, if we increase the web thickness
of the 5i' X 5i" X 23-4 lb. section from 0-31' to 0-63', we must proportionately
increase the flange thickness also, viz,, from 0'47'' to O'fii", It will be a[>parent from
Fig, 6 that the 0'i)2" increase in the ueb thickness will incrta&e the tiidth of the s^-ction
by the same amount ; and that jiurtabing the flange thickness by 0- 47" will increase ttie
depth of the section by twice 0-47".
Accordingly, the dimensions (to one decimal place) will become 6*5' x 5- 8' (see
section YoACM, page 16),
The simple calculations required fur determining the increase in sectional area and
moment of inertia will also be apparent from Fig. 6; but, for practical puri>ases,
sufficiently accurate results can l>e obtained by interpolation.
N.B. — Intermediate and Dm (nmxinunn) weights are not obtainable in smaller
quantities than the " minimum lots " tabulated on page 286.
MAXIMUM WEICHTS-
The ability to produce these sections with greatly thickened webs and flant;c:i ii
particularly useful —
(fl) For the lower stanchions in tall buildings,
(6) For girders which would otherwise have to be plated on account of limited
headjoom. Thus, in a Bristol factory, 463 tons of the 28' x 12' section were
used, increased in this way from 171 to 201 lbs. per foot.
[c) For machinery bedplates, especially when the upper flanges have to be planed
to a dead level.

These special sections with extra wide flanges can be supplied, from rolls, as readily as the
standard sections if ordered in quantities of at least 2r)0 feet of a size.
For safe loads ubeo used as Stancliioos see page 92 ; as Poles, page 154.

WEIGHT PER FOOT. As explained on page 11, the various sections are rolled in
four standard weights— known as the Die, Dil, Din and DiR weights — and can also
be rolled to intermediate weights, of which some typical examples (marked (") are
included in the table.
(i) The first line in each group is the Die or minimum weight ; for most pur-
poses the minimuni weights are to be preferred.
(ii) The second line in each ^oup (up to 24" x 12") is the Dil section. This
is similar to the former standard weight {Din series) but has a reduced web.
(iii) The weight directly opposite the nominal size is the Din or medium
weight (formerly the standard weight).
(iv) The last line in eacli group is the Dm or maximum weight,
(v) Weights marked : in the " Delivery" column are t^'pical intermediate
weights.
DELIVERY. The various weights of each section are produced by merely varying
the spacing of the rolls. Accordingly, all the Wrights can be obtained (from
rolls) equally readily ; and in any desired quantity, except as mentioned below.
(i) The DiR series (mx-dinum weights), marked " r " in the " Delivery "
column, can only be supplied In lots ranging from 3 to 9 tons minimum, according
to section (see table on page 286).
(ii) Intermediate weights, including the tjrpical examples marked " i " in the
tables, can only be supplied in lots ranging from 18 to 36 tons minimum according
to section (see table on page 2H6).
The other symbols in the " Delivery " column have the following meanings : —
• Xormally stocked in the U.K. (but see page 6).
a Average rolling dates 3 to -4 weeks.
h „ „ ,. 4 to 6 „
C „ „ ., 6 to 8 „
ECONOMY. The Die or minimum weights are the most economical ; i.e. shew
the highest ratio of capacity to weight, both as beams and as columns.
SECTIONS WITH EXTRA WIDE FLANGES. As columns, the Special sections
listed on page 20 are even more economical than the standard sections, and are
as readily obtainable if ordered in fair quantities.

e. WEJGHTS PER FOOT.
The various weights listed for each section are : —
( i) Up to 24' X 12', the Die. Dil, Din and Dm weights respectively, as explained on page 21.
(ii) Above 24' x 12', the Die, Din and Dir weights respectively.
These are all obtainable with equal facility from the mills, except that the DiR (maximum)
weights can only be supplied in the minimum quantities specified JD the table on page 286 ; the
weights readily obtainable in small lots from local U.K. stocks are those marked with an
asterisk in the " Delivery " column. For most purposes, the minimum weights should be
preferred, as being the most economical.
7. INTERMEDIATE WEIGHTS.
All sections can be rolled to weights intermediate between the tabulated minima and
maxima, subject to the conditions explained on pages 11 and 286.
8. DELIVERY.
The meaning of the symbols is as follows, but see page 6 :—
{•) Stocked in the United Kingdom.
(a) Average rolling dates 3-4 weeks.
(i) .. .. .. 4-6

SUMMARY OF GIRDER SECTIONS
EXPLANATION.
Tables of safe distributed loads for Broad Flange Beams and Joists will be
found in their respective chapters.
An alternative procedure is to calculate the Bending Moment, and thence the
required Section Modulus (Bending Moment divided by working stress)^; then
to select a suitable section from the following table, in which the various sections
are ranged in order of Section Modulus. It is needless to say that shear, deflec-
tion, and lateral stiffness may also have to be considered.
Wliere economy is the main consideration, it is necessary to bear in mind the
considerable difference in cost per ton between plain rolled steel beams and
built-up girders.
The tabulated weights allow for rivet heads, but not for stiffeners or separ-
ators. Rivet holes (in the tension flange) are allowed for in the tabulated Section
Moduli for plated beams. In the listed depths, rivet heads are disregarded.
The delivery sjTnbols are to be interpreted as follows : —
* = Stocked in London and elsewhere.
a = Average rollings 3-4 weeks.

= Intermediate weight, 18 to 36 tons minimum (see page 286),
= Maximum weight, 3 to 9 tons minimum (see page 286).

y ^ Rollings irregular.
N,B. — These indications of the time required for delivery reim to normal
pre-war conditions. For the present position (1948), see note at foot of page 6.

4. SHEAR. The (orce tending to ibear vcrltcaJly through the «irder
is greatest at the ends, there equalling the ^nij reaction. Tbe shear li
decreased at every point of loading by the amount of thic Joads ;sce Tig. 2),
5, BENDING MOMENT. At any distances from tlic Jcfl. the bendiug
mometit al that point equiUs the difFerence between the moment due to
the TpaciJon and the reverse moments due to the loads to the left M
the point, tlie moment being the product oJ the I,oad or iteaction and ita
distaDLie from the point.
6. SENOINQ MOMErJT DUGRAM, Thb is coEislructedbv drawing a
line proportional to the girder length, and setting up at right angles to
it lines proportionat to the bending moments at the various points of
l^>ading. and joining the exttenijljcs of the lines so dr^wn (Fjg, 3]. For a
uuitonnly distributed load, the boundiog line thus formed is a parabola,
7, DEFLECTION. If a tangent to the deflection curve be drawn at a
point distant x (Inches) from the left, and
I = the vertical distance of tliis line from the support
(^ Fi§. 4). '^'^
H = the FiasLic M'>dijlns of tlie mikt>?ri.U.
1 == the Moment of loertia oi the girder taken as constint
throughout ita Icagth
then £ £1 » the area of the portion of the Bendini; M'oment Diagram above the length x multiplied by the
dista,nce O of the pcenlre of gravity of this area from the ieJl rt-action.
This e^iuation gives a ready means of Ending points on the dedect^oa curve, when the Bending Moment Diagram
U drawn.*
If the girder is not of uniform section so that the Moment of Inertia is not coustant, the Beading Moment
Diagram can be '" corrected "' by increasing the vertical ordiiiiiles in the ratio of maximum tu actual Moment of
Inertia, and then making 1 in the e<iu^tion equal to the maxmium Moment of Jncrtia.
The deflection *o calculated is that due to flexural str«s only. The shear stresses also cause deflection but only
to a sra^ali extent in the relatively long spans vriicre deflection is of importaucc.
Nevertheless, when the elastic modulus is c^culated from deflection tests, a lower value Is usually found than
from tests, in direct tension^
On these gTounds it will sometimes be desirable to assign a reduced value to E for the purpose of calculating
deflection ; thus, E could be taken as 12000 tons instead of its actual value of about 1I4UU0 tons per square inch.
3. OTHER END CONOITIQINS. H the ends are fixed, there will be upward bending moments at the supports -.
the Bendme Moment Diagram can be constructed by first drawing aa for supported ends, and then raismg the base
hue to pass through the citremities of the lines representing the end bending moments (Fig. 6). This new tjase
line will intersect the original bounding line at points where tlic bending moment is zero, known as the points of
con trail ezu re ^
In the formulae on pp. ^5 to iS the end bending moments have been calculated by the principles of { 7,
awummg Ihiil IJie tangent to Uie deflection curve at one support posses through the other, c^ccepl, of course, for
i^ntilcvcra. vcherc the cod bending moment is the product of the reactjon ami the distance of the centre of gravity
of the load from the support. The bending moment at on« end of tlic beam will increase the reaction at that end and
diminish it at the other end by an amount equal to the quotient of the bending moment and the length of tbe beam.
9. CONTINUOUS BEAMS. The end bending moments for coutinuous beams can be calculated by using the
principles of ( 7 and equating the two expressions for the inchn-itLon of the beam at a support, io terms of the speru
ou each fide of the support^ or by means of the coci&cieDtd givcu in the diagram on page 60.
* The maximum defection never differa greatly from that at the centre of the span. When the ends are
restrained the central deflection calculated lor a freely supported girder is reduced by the average of the end bending
coijinents x span* ^ d El.

CONTINUOUS BEAMS
The coefticients shown in the following diagrams are based on the Theorem of Three
Moments and presuppose strict comphance with the foUowing condiUons :— (a) That the loads
are equal and umfomilv distributed over the spans, (fc) That the effective spans are equal.
Ic) That the column caps are in the same plane, {d) That the beani is of umform section.
The specified Reaction and Shear coelfitients are in terms of W ; the Moment coefticients are
in terms oi Wl. ,.,.,... j
When weighing the relative advantages of continuous and simple girders in a given
instance, the following pomts need to be considered : (1) The possibility of the actual load
and distribution diflering from those calculated. (2) The column reactions being unequal, some
of the columns u ill have to be stronger and stiffer than for simple girders. \'d] The position
of maximum shear coincides with that of maximum bending moment. f4) XSTiether it is
necessar\' to provide for expansion. (5) Heavy freight charges and site difticulties arise with
long and heavy pieces r these will be avoided ho^\ever if bean.s of normal length are made
continuous by'sile-welding. (6) The foundations must be exceptionally good, so as to pre-
clude unequal settlement. (7) In riveted construction, the columns will have to be broken at
each storey. (8) The advantages are rigidity, reduction of girder section, and reduced costs
of iabricatioD.

NOTES ON GIRDERS.
K LATERAL STABILITY.
If the top flangt' of a girder is not suppjrt-d siiewaj-s at intervals of at most 20 times
the flange width, the working stress should be reduced, by a percentage equal to tAvicc l/b — 20,
where l/b is the ratio of span to flange width, thus : —
For ratjo l/b = 25 30 35 40 45 50
Keduction = 10% 20%
30%
40% 50% 60%
Ttese percentages coincide with the provisions of the London County Council Bv*Law3
(and B.S S. 449, § 10) ; see page 281,
For Broad Flange Beams 12' X 12" and upwards, alt of which have flanges 11 '8', the
value of i/b is approximi^lely the same as the span in feet.
2. ECCENTRIC LOADS.
When an eccentric load tends to cause a girder to twist, the bending moment (load
multiplied by eccentricity) may be considered as setting up a lateral thrust in opposite
directions on the ti-p and bottom flanges, equalling the l>ending moment divided by the girder
depth.
These side thrusts will set up horizontal bending moments in each flange, and the st
due to these must be added to those due to the vertical bending moment produced by th'
considered as centric.
3. LIVE LOADS IN BUILDINGS.
In building Construction, the li\e load on a floor is usually treated as equivalent to an
assumed dead or stationary load, distributed uniformly over the Moor area.
The London County Council By-I^ws <and B S S, 449) also require floors to be capable ni
supporting appropriate concentrated loads— see page 280, § «a and special table on page 2'28
For floors carrying machinery uiih heavy moving parts, special calculation is necessary.
4. TEMPERATURE LENGTH CHANGES.
In Bniain, the maximum range of temperature in structural work exposed to the w«ath«r
is about JOO* R In buildings, hoi*evcr, the range will rarely be so great*
For a change in temperature of UW i: the change in length of structural steel will be
1/8' jn a length of 15j Irrl approx.
In long stretches of steelwork, expansion must l>e provided for bv means of clearances
and slotted hole&,

NOTES ON GIRDERS.— Continued.
5. CRANE GANTRY GIRDERS,— Continued.
The effect of applying a load suddenly is to double the stress it wmld produce as a
stationary load.
In the case of moving cranes, the maximum flexural stresses in the gantry- are reached
gradually, and the maximum load on the end carriage rarely occurs when the crane is travelling-
It is now considered sufticient to add 20% of the wheel loads, as the allowance for impact, or
25% for cranes lifting 5 tons and upwards. Some makers add only 10%.
The position of maximum &hear stress is reached when, with the leading wheel of the end
carriage on the gantry, the rear wheel passes on to it from the next span ; as the load on thi9
wheel is applied suddenly, it must be added to the shear due to both wheels to obtain the
equivalent stationary shear stress.
The effects of cross travel and cross drag should be considered in conjunction with the
most unfavourable conditions of loadmg. They may be taken as equivalent to a static load P
applied horizontally to the top flanRcs of the two gantrj- girders, where P = 15% of the
combined weight of the load and crab.
The horizontal pressure P may be assumed to be distributed equally between the lop
flanges of the two girders, unless the frictional grip F (taken as 20% of the load on the end
carriage wheels) between the rail and the more lightly loaded wheels is less than P -f- 2. In
such a ca^e the girders must be proportioned to withstand a side thrust of P — F.
When the unsupported len^^h of girder is more than 20 times the flange width, the working
stress must be reduced, see § 1 on previous page, or the top flange strengthened.
This is not usually necessarj' in the case of B.F- Beams, but when the
compression flange of a deep B.F. Beam is found to require lateral
stihenjng, a 15' x 4' channel riveted web uppermost to the top dange of
the beam {Fig. 1) is a very efficient arrangement.
The inertia effect due to the sudden stopping of a rapidly moving
crane should be taken as equivalent to a stationary thrust along the
rrane girder equal to 20% of the load on the rail. This thrust must, of
course, be resisted by the stanchions carrying the crane girder.
The advantages of B.F- Beams as girders under crane runways are :
(i) The useful range of sizes up to -10* deep, with 12' flanges,
(ii) Lateral stiffness increases in proportion to the square
of the flange width, so that the I -Se" flanges of a 24" x 12"
B.F, Beam, for example, are over three times as strong
laterally a*i the J' flanges of a standard 24' x 7i* R.S, Joist,
fiii) They afl^ord a flat ?;urface. free from rivets, for
bolting on the crane rails. Compare Figs, 2 and 3.
The average weights and dimensions of cranes are
tabulated on page 54.

8. RAILWAY BRIDGE GIRDERS.
For comparatively short bridge spans, the effect of impact from all causes (unbalanced
driving wheels, irregularity of track, suddenness of application of load, etc.) may be taken as
doubling the actual train load.
The overturning moment due to wind pressure on the train increases the vertical Inaul
on the leeward girder and decreases it on the windward. The wind load (say 30 lb. per square
foot of exposed vertical surface) may be taken as 3cwts. perfoot run actmg as a horizontal
load T 6' above the rail.
The efiect of sudden application of the brakes may be taken as equivalent to a suddenly
applied load equalling 20% of the weight of the train, acting along the rails and resisted at
the end bearings.
When the rails are on a curve, an outward horizontal thrust is set up by the moving train.
If W = weight of train,
i; = speed of train in miles per hour,
r = radius of curvature in feet,
the side thrust = Wv' -5- 15 r and may be assumed to act in a plane 5 feet above the rail level.
This thrust will have a similar effect to the wind load and must be allowed for in conjunction
with it.
Broad Flange Beams, Grey Process, especially sections 24* x 12' to 40' x 12", have been
employed extensively as main girders in railway bridges of spans up to 40 feet or so ; the
smaller sections are used as rail bearers and cross girders in larger spans. The saving in weight
and cost of workmanship a^ compared with plate and angle girders is considerable, and the
cost of maintenance is also reduced owing to the diminished liability to corrosion of a solid
steel beam.
9. ROAD BRIDGES.
In road bridges the unevenness of the surface greatly intensifies the stresses set up by
vehicles, and the equivalent stationary load should t* taken as double the moving load.
Ordinary traffic on portions of the bridge not occupied by the wheel loads may be taken
as equivalent to a stationary load of 1 cwt. per foot super, increased to IJ cwt. for a distance
of S feet out from each parapet.
The effect of wind pressure on the main and cross girders must also be considered, but
the bridge fioor itself will usually constitute a more than adequate wind bracing.

The safe compressive stress of concrete may be taken as 5A -|- 300 lb. per square inch,
where A is the weight (lb.) of Portland Cem.ent to 2 cubic feet of fine and 4 cubic feet of course
aggregate ; this is one-third of the crushing strength to be shewn on test at 2S days with
ordinary, or at 7 days with Rapid Hardening Cement.
10. GIRDERS CARRYING BRICK WALLS.
Usual British practice is to design the girder to carry a uniformly distributed load t-qual
to the weight of the brick^'ork enclosed in an equilateral triangle with the span as base, though
after the brickwork is set, the actual triangular load on the girder will have a height of only about
1 /3rd of the span.
If floor or other loads come on the brickwork immediately above the opening thvymust,
of course, be added to the weight of the brickwork.
The deflection in girders carrj-ing brickwork should be limited to I/500th of the &pan

For purposes of calculation it is assumed that the pressure is uniformly distributed over
the contact surface thought actually, the deflection of the girder tends to concentrate the pressure
on the edge, which should accordingly be chamfered.
The London County Council and British Standard Specification 449. base the allowable
pressures on the ascertained crushing strength of the bricks or stone used. For bricks in cement,
the allowable pressures range from 4 to 40 tons per square foot, according to the quality of the
bricks and composition of the mortar. These pressures have to be reduced for walls or piers of
which the height is more than six times the least dimension : thus, for eight times, reduce by
20% ; for ten times, reduce by 40% ; for twelve times, reduce by 60% (see page 39 of B S.S,
449, extracts on page 285 hereof),

13. STEEL BEAMS AS TEMPLATES.
Rolled steel bearns are sometimes used to distribute a heavy load over brickwork.
B F Beams Grey Proi<-i,s. are useful for this purpose, and a table is given on page (.3 shtNnng
the "rciuired sections and lengths lor various loads. The mode ol calculation is as follows :—
(i) The area of contact surface must be such as to limit the pressure per square foot on
the brickwork to a safe figure— e.g., 10 tons per square foot on hard bricks laid m cement.
(ii) The flexural. shear and transverse stresses in the template beam are calculated on
the assumption that the template beam acts as a pair of cantilevers, each bearing a distributed
load equal to half the total load.
(iii) The principal compressi\e stress resulting from the combined flexural, shear and
transverse stresses must not exceed the safe princiiJal compressive stress, as tabulated for
B F Beams on page 38. and for ordinary steel joists on page 137. This is the factor determining
Ihe sues and lengths tabulated on page 63 ; the Hexural. shear and transverse strcssts,
separately considered, arc well below the allowable limits.
(iv) U the load on the template beam were actually concentrated at a point, as in Fig, 1.
the -web cf the beam would be liable to buckle as a column by direct pressure. But in practice.
Fl<. 1.
Fig.
the load on the teniplaio beam will almost always be distributed (as in Fig 2) over a length
■■ i ■' ol the template sufficient to keep the pressure within safe limits.
In exceptional cases the sufficiency of the web can be investigated as in g 4, page 62.
!4. STIFFENERS.
I
AMien stiffencrs arc employed, the concentrated load or end reaction, as the caAC may
be, must be regarded as divided between the siiflencrs and the web in proportion to their
respective capacities
Tu'O an^lea, one on each side of the web. make the n^ost effective atiffeners, and as the
radius oJ gVTaiion oJ the pair about the centre of the web will be fairly large, except for
deep plate girders, the required area of the angles may be safely taken as I square inch per
NOTES ON GIRDERS.— Continued.
5} tons of load without further investigation The angles shuuld be ground to fit b<:tvveeu
the flanges at top and bottom and be connected to the \\eb by a sufficient number of nveis at
a pitch not greater than 5*. to take up ^vhatev-e^ proportion of the load they a^e assumed to
carry. This proportion, in the case of Rolled Steel Beams, may be safely taken as 50% (of
the reaction or load, as the case may be).
For Plate Girders it is better to regard the capacity of the iveb for resisting compression
due to direct load as ml, so that stiffeners should be put at all points of concentrated loads
and reactions. In this case, besides stiffening the ueb against buckling and transmitting
the load or reaction to the web, they act as connections t3et\\een the top and bottom flanges,
stiffening the compression fiange against local buckling and lateral flexure.
The spacing and size of the atiffeners are usually determined by various practical con-
siderations, but generally the centres of the stiffeners should not be greater than the depth
of the girder. See also page 284 {" B.S S. 449 ").
The uebs of B,F. Beams, Grey Process, are designed of sufficient thickness to avoid the
need of stiffeners under usual conditions of loading. Stiffeners on plain rolled sleel beams
are relatively costly, since to fit them usually entails extra handling and carriage from mills to
the constructional yard.
16. FLOOR GIRDERS IN BUILDINGS.
Broad Flange Beams are employed M'ith advantage as floor girders in buildings, in such
cases as the following : —
[a) If the span and load are beyond the capacity of ordinary' sfeel joists,
[b) In cases where the depth of an ordinary joist would be so great as to necessitate
riveting angle shelves to the web to carry the flooring, a considerable saving
in cost can be effected by substituting Broad Flange Beams, which usually
enables such angle shelves to be dispensed with.
[c) In some cases, the extra weight of steel involved in using a shallow girder is more
than compensated for by the saving in cost resulting from a reduction in the
thickness of the floors and consequent reduction in the total height of the building.
(rf) In some types of fire-proof floorings the ample bearing surface afforded by wide
Banged beams is essential ; in such cases, the fact of the flanges being without
taper is an additional advantage.
Fig. 1 shews a typical use of Broad Flange Beams in conjunction with ordinary round
steel reinforcing bars.
Fig. 2 shews a similar arrangement, using an OTdinary rolled steel joist of the same carrying
power ; the superior bearing afforded by the Broad Flange Beam in Fig, 1 is obvious.

STRESSES IIM GIRDERS.
]
I FLEXURAL STRESS.
The various tables of safe loads are for beams freely supported at both
ends and bearing a uniformly distributed load. The diagrams and formulae on
pages 45 to 49 provide a ready means of calculating the safe loads and
deflections for many other conditions of ends and loading.
The simplest means of providing for irregular loading is to ascertain, by
calculation or graphically, the maximum bending moment and shear. The
former divided by the allowable flexural stress — e,g,, 8 tons per square inch — is
the required section modulus, as given in the tables of properties of the various
sections of beams, channels, etc.
2, SHEAR STRESSES,
The vertical and horizontal shear stresses are equal at any point in a cross
section ; they decrease from a maximum at the neutral axis to zero in the extreme
fibres of the flanges.
The average vertical shear stress is found by dividing the total transverse
shear by the web area (depth of beam y web thickness). The maximum
vertical shear stress — at the neutral axis — is about 12^% greater.
The " maximum distributed loads " tabulated on pages 30 and 174 are
based on an average shear stress of only 4 tons per square inch, so that the
maxmium ^tress shall not exceed 4} tons per square inch.
If t = Thickness of the cross section at the point under consideration.
A = Arcaof portion of section between the point and the extreme fibre,
a = Distanceofthecentreofgravity of this area, from the neutral axis,
I = The moment of inertia of the whole section a»>out the neutral axis,
S = Total transverse shear {i,e,, vertical shear in a horizontal girder).
s = Shear stress intensity {transverse and longitudinal),
then s = (S X A X a) -h [t X 1).
This formula has been used for obtaining the rivet shear factors tabulated in
the plated girder tables on page 250, assuming a shear or t>earing stress of
fi^ or 11 tons respectively.
3. COMBINED EFFECT OF FLEXURAL AND SHEAR STRESSES-
fi) In cases where high flexural and shear stresses occur at the same point. •
besides considering them independentlv, it is necessary also to consider their
combined effect. They may be resolved at any point into two stresses, compres-
sive and tensile respectively, one of wh<ch is the greatest stress U> which the
material is subjected at that point. These tivo stresses are termed the " Principal
StnaSM/' Their values are J ±x'^i* 4-''^ where /= the flexural stress and
* = the vertical shear stress at that point.
The principal compressive and tensile stresses attain their maxima at the
junctions between the web and^the upper and lower flanges (i.*,, at the fiUcU)
respectively; these maxima are of equal numerical value.

Consequently, as the allowable compressive stress in the web (owing to ita
buckling effect) is less than the allowable tensile stress, the latter may be
disregarded.
To calculate the maximum principal compressive stress in a beam, we have
first to determine at what position in the length of the beam the combined
effect of shear and flexural stress attains its maximum* and then to determine
the value of the principal compressive stress at the upper fillet in this cross
section.
To find the values of/ and s at this point, we have ; —
If F = the extreme fibre stress in the cross section under consideration,
d = total depth of beam,
c = depth of web between fillets, see Fig, I,
then / = F X ^
N.B. — The values of , arc tabulated on pages 38 and 175 for
Broad Flange Beams and R.S. Joists respectively.
The value of s at this point may be taken as the total transverse shear (at
the cross section under consideration) -f by the web area, namely, hy d X t,
where t is the web thickness.
Substituting these values of/ and 5 in the formula on page 60, if the
maximum principal compressive stress, thus calculated, exceeds the safe
principal compressive stress (tabulated for B-F. Beams and R.S, Joists on
pages 38 and 175) then a larger section is required, or else the web of the beam
must be suitably reinforced throughout the requisite length up to a point where
the stress falls within safe limits.
(ii) The safe principal compressive stresses tabulated on pages 38 and 175 are
calculated on the following basis : —
The web is assumed to be analogous to a series of struts and ties perpendi-
cular to each other and set at an angle of 45'' to the neutral axis. The ties
brace the struts, and this is assumed to be equivalent to halving the effective
length of the struts. Accordingly, the safe principal compressive stress is
taken to be the safe compressive stress on a column with fixed ends, of
length equal to one-half of the depth of the web measured between the
fillets at an angle of 45* to the axis of the beam; viz., of length
c ^
2 X \^2, The stresses are calculated by Fidler's formula with a factor
of safety of 4, as tabulated on page 95,
•This to usually s^lf-evident, and. lor U>e ina}orit7 of the eonunoner cas^s of loading, can be
readily deduced from liic abeariog force and bending moment diagrams given on pagea *5 to 4a

(iii) The shear stress (sj— resulting from combined flexural stress and vertical
bhear stress at any point— is at a maximum at an an gle oi 45 to the principal
r Ji
stresses, in which direction its magnitude is V5'+ 4 . namely, half the algebraic
difference between the principal stresses. It should not exceed i^ tons per
square inch. . . ^ *i_ • ■ !• '
In any cross section the value of s^ will always be greatest at the junction
of web and flange, and occurs normally, but nut necessarily, in the same cross
secUon as that in which the principal compressive stress attains its maximum.
4, TRANSVERSE STRESS.
When a girder carries a hea\->' concentrated l<iad it is necessary not only to
consider the combined effect of the flexural and shear stresses, but also the
liability of the web to buckle locally as a column. This liability has always to be
considered m template or grillage beams, but may also arise with any exception-
ally short heavily loaded beam, either beneath the load or at the bearings.
Such cases must be examined from two points nf view : —
(i) If the pressure on the web exceeds the usual allo%vancc of 11 tons
per stjuare inch (bearing value), the bearing area must be increased
by ap]>l>ing plates or stiffeners properly ground to fit between the
flanges.
(ii) If the ;»tress per square inch in the web exceeds its safe compressive
stress as a column, either the web area must be increased by plating
or stilieners designed on the lines indicated on page 58 must be
added.
Tlie " safe column stresses " for the webs of B.F. Beams and ordinary
joists are tabulated on pages 38 and 175 respectively- They are calculated by
Fidler's formula for columns with fixed ends with a factor of safety of 4, to be
increased by 50^;, ** there is an}- vibration or impact.
Inasmuch as the pressure on the web is distributed and ultimately converted
into a shear stress, it may be assumed for purposes of calculation that the
pressure is spread over a greater length than the actual length of web under
compression.
Thus, if d is the depth of the beam and / is the actual length of web in
compression, then, in the case of an end reaction (l-ig. 2), the pressure may be
regarded as distributed o\'er
alenj;th/+0-3rf.
In the case of a concen-
trated load as in Fig. 3, this
addit inn to the effective
length may be regarded as
occurring on both sides, so
that the length under com-
pression may be taken as
/-f 0-6d.

B.F. BEAMS, GREY PROCESS, AS TEMPLATES.
Rolled steel beams can often he employed with advantage to distribute a htavv load over
a aufticient area of a brick wall or pier, as illustrated in Kn,'s I and 2.
In the table below, we shew what sections and lengths of 11 F Reams, Grev Procesg. are
suitable for various loads, and for an allowable pressure cm the brickwork of o'. 8 or 12 tons
per square foot, as the case may be. These are the maxiiimm jircssures ordinarily allowed
(see page 57 § II), for

(i) Ordinary bricks in

(ii) Hard (including

(iii) Blue bricks in

USE OF TABLE. — Suppose a steel template is required to distribute a load of 50 tons,
on hard bricks laid in cement, the allowable pressure being 8 tons per square foot.
The table shews that a B F, Beam 14' x 12* x 101 lb y 6' 1 1' long would be suitable for
a load of 54-6 Ions. Tor a load of 50 tons, the length can be proportionately reduced, viz..
to 6' 4*.
Alternatively, since the table shews that a beam gj' x 8J' x 48 lb X 4' 4' long would l)e
suitable for a load of 25 tons, a pair of these could be used instead for the 50-ton load, if more
convenient.
When used in pairs, template beams should be joined together with separators, as shewn
on page 74 {or, for ordinary' joists, on page 82).
IVIODE OF CALCULATION. — The template beam is regarded as a double cantilever,
carr^-ing a uniformly distributed upward load ; and the section of the template beam is
determined by the principal compressive stress resulting from the combined riexural. shear
and trans\'erse stresses in the web. For the loads tabulated below, web stiffeners are not
required. For fuller explanation, see page 58.

CLEATS AND FISHPLATES
BEAM SECTIONS.
The connections shown for B.F, Beams, on pages 67 to 73, are designed to suit
the DiN (medium) weights. They can readily be adapted to suit the other weights.
SAFE END REACTIONS-
Tbe Stated safe end reactions are the shear values of the connecting bolts, taken
as; —
4 tons per square inch in Web Cleats.
2 tons per square inch in the Upper Flange Cleat.
A low value is taken in the latter case, on account of the considerable tens3e
stress in these bolts.
(N-B- — The shearing and bearingvaluesof the web rivets, taken as 5 J and 11
tons per square inch respectively, are greater than the shear values of the bolts.)
In the absence of diagonal wind bracing, web cleats are useful for stidening the
structure, especially during erection. They should not therefore be dispensed with,
even when the beam rests on a bracket designed to support the entire end load,
CLEATS.
The supporting bracket or lower flange cleat is not shown in these drawings
because it will usually be riveted to the supporting member. The upper flange
cleats here shown have fur their primary function to provide a more rigid connection,
in the interest of general stability.
The stated weights are finished wei^jhts, exclusive of field bolts or rivets.
FISHPLATES.
Ihese are suitable for an urdinar>^ connection over a stanchion or other support ;
but when a joint is not over a support, flange plates must be fitted, at least equal
to the calculated bending moment at that point (it is more usual to design such splices
to equal the full resistance moment of the beam). It is usual to allow about j'
clearance between the abutting ends of the beams, thus ;—
In the case of a long stretch of girders, as in crane runways, provision must be
made for expansion— usually by slotting the holes in tlie fishplates, and making an
appropriate allowance in the girder lcng:ths. The variation in length caused by a riw
or fall in temperature of fiC* Fahrenheit is i' in 31) feet.
The stated weights are the calculated weights ol the plates, bolts, and nuts,
less holes in plates and beams.

NOTES ON STANCHIONS.
K TABULATED SAFE LOADS,
In the present edition, the various tables of sAfe loads for columns are all calculated by
the British Standard formula (B.SS. 449. 1937) : for mUd steel, and for " both ends held in
position but unrestrained in direction/' which is equivalent lo assuming hinged ends. The
same stresses have been adopted in the London County Councirs By-Laws (1937)*, They
are tabulated on the opposite page ; and with them, for comparison, the stresses calculated
by Fidler's formula for fixed ends,
2. END FIXING.
In the chapter headed "Tests, Extras" will be found notes and extracts from BS.S.
Xo, 449 (§16), giving definitions of end fixing and effective length. In general, if the ends of
a Dilumn are not " fixed/' the effect is the same as increasing the length of the column ; the
following are the appropriate multipliers according to various authorities.
EuUr. Fidkr. B.S.S,
Both ends fixed 1 1 *7
One cad fixed, one hinged 1-1/3 1-1/4 -86
Both ends hing<^d 2 1-2/3 1
One end fixed, one free 4 3-1/3 1 to 2
The assumption of fixed ends-— even with the reduced multiplier^ proposed by Fidlcr and
the BS.S, — should be made only uhen the conditions are exceptionally favourable, as in the
bottom tier of interior stanchions in a steel frame building of moderate height, where the
stanchions are connected to girders on all (our sides, and the loading is sjTiimctncal,
B S.S. 449 — 1937 says that a column may gen<"rally be assumed to have its end " held in
position " (hinged) when the resistance moment of the restraining member and its connections
is equal to - 25 of the resistance moment of the compression member (as a beam w ith 8 tons per
sq. inch extreme fibre stress) for values of / g up lo 120 ; or, for higher values, the resistance
moment multiplied by -25— -Oli (l/g — 120),
Up to a length of 120 //g a column wjtha fixed, flat, or square end. soaj to distribute the
load unifomjy over the entire area of its section, may generally be assumed lo have an end
connection with a moment of resistance equal lo ■2J5 of the resistance moment of the compression
member and to be edeclnely restrained (against crippling due to a?cial loading). If the length
exceeds 120 l/i, the ends may generally be taken to be partially resuained.

3. CHOICE OF SECTIONS.
WTicre saving of space is the main consideratioo, the choice may be bct^veen employing
girders over long spans without intermediate supports, or using solid round steel colunuis^
despite the considerable extra cost involved.
Where economy and stability arc the main considerations, the most advantageous sections
for loads ranging from about 10 to 300 tons are Broad Flange Beams, Grey IVocess.
For smaller loads, a light rolled sleel joist fc g., 4' x 3') may suflSce ; for greater toads some
form of built-up stanchion will probably be required.
The economy of Broad Flange Beams, square in shape, compared with such joist sections
as C X 5', 8' >: 6', 9' x V and 10* x B' is clearly shown by the foUouing instances, the loads
beinr; calculated by the same formula (B S S , as employed for the various tables in this book)
and for the same length, here taken as 1 2 feet : —
0) R.SJ.8' X C X 35 1b., safe load 37 tons ; B,F B. 7-5' x 7-8* x 30- 1 lb. safe load
46 tons.
(ii) R S J. 10' X 8' X £5 lb . safe load 81 tons; BT.B,Q-8' x 10- 1' x 46 lb , safe load
83 tons.
Here we have a saving in weight of 14% and 16% respectively ; and in the first example
a 24% increase in strength.

NOTES ON STANCHIONS.— Continued.
If similar comparisons be made for stanchions of greater length, the economy of the
Broad Flange Beam is still more conspicuous. Thus, for a load of 44 tons and a height ol
16 feet, the diSerencc between R.S J. 9' x 7' x 50 lb. (safe load 15 tODS) and BT.B. 8-3' X
8-5' X 34i lb. (safe load 44 tons) is a saving in weight of 31%,
When comparison is made with built-up stanchions, composed of steel joists or channels
with plates riveted (or welded) to the flanges, the main economy of the Broad Flange Beam
is in the ehminatioD of expensive labc^urs, as illustrated in the case cited on page 8 (Fig. 2),
uhere the use of the plain B.F. Beam shows a saving of 7J% in weight ; the elimination of
122 rivets, and a stil! greater number of drilled holes; and only one piecc^ instead of four
(at least), to be straightened and cut to exact lengths.
In addition to the economy they effect, B,F, Beams offer other general advantages,
such as the facilities for connections afforded by their wide flanges and diminished liability to
corrosion as compared with riveted stanchions. Moreover, stanchions of plain rolled steel
sections can, of course, be produced much more rapidly than riveted stanchions, sometimes a
very important consideration.
Subject to the minimum quantities specified on page 286, the lower tiers of columns in
a building can he in the same section as the upper tiers, but rolled to maximum or intermediate
weights (see page 11).
4. ECCENTRIC LOADS-
The tabulated safe loads and stresses are for stanchions centrally loaded. If the loading
be one-sided as in Fig, 1, or unbalanced as in Fig. 2, a bending moment is set up in the
Fig. 1
FIC. Z.
stanchion, which increases the compressive stress on tbc near side of the itanchioo. while
reducing it on the opposite side.
The principle adopted is to hmit the maximum compressive stress in the sUnchion to
that which would be allowed— over the whole area of the stanchion — if centrally loaded.
The multipliers (or eccentric loading given in the tables of safe loads enable this principle
to be applied in a very simple manner, as explained below.
In the London County Council By-Laws (and B.S.S. 449) eccentricity of loading
is provided for in similar fashion, but the maximum compressive stress ia allowed to exceed
that permissible for a central load (see page 283 ti 17}.
5. ECCENTRIC LOAD IVlULTIPLIERS.
In the Tables of Safe Ij^ads, " EccenUic Load Multipliers" are given (or flange and
web connections resi>ectively.
In cases where the eccentric load is transmitted by a prder cleated to the itanchion,
as in Figs. 3 and 4, all that is required ii to multiply the load by the appropriate multiplier in
order to ascertain the equivalent ctnttat load.
Thus, if Fig. 3 represents a sunchion with fixed ends of 12' y 12' section, 19 feet
high, aod the load transmitted by the girder is 50 tons, the equivalent central load mil be
SOx2'35 = ll7i ton^ (2'35 being tbc eccentric load muliipUcr (or a flange conaectioo. as
Ubulated on page >44).
The Table of Safe Loads (page 87) shf-wi that the safe central load is 122 toat, and,
therefore, that the 12' X 12' tcction is luiUble.

6. BENDING MOMENT MULTIPLIERS.
The " Eccentric Load Multipliers " are only applicable to the case of eccentric loads trans-
mitted by girder* cicated to stanchions, as in Figs- S and 4. Tlicy assume that the point of
application of the load is at the face of the stanchion a* shewn.

This assumption is inadmissible if the girder b merely supported on a projecting bnicket as
in Fig- S or iii Fig. 6.
In such cases, and where bending moment is induced by wind pressure or oth^r
horixontal thrust, the procedure is to calculate the bendmg moment and multiply this by one
of the tabulated " bending moment multipliers," in order to arhve at the equivalent ceatr^
load.
The procedure is equally simple In Fi<s. 5 or 6, if the eccentric load (W) is 3u tons and
the distance o( the point of ap; jn # is 12 inches, then the bending momrnt is W x #
<- 30 X 12 « 360 inch-tons.

If the section under consideration is 12' X 12*. of which the tabulated bending monient
multiplier (XX) is 023, the equivalent central load is 360 x 0-23 = 828 tons-
This only represents the additional equivalent central load due to the bending moment ; we
must therefore add the actual load in order to arrive at the total equivaltat central load, which
w^U accordingly be 30 + 82'8 = 1128 tons.
Assuming the stanchioQ to be 20 feet long and fixed at both ends, the table ol safe loadi
on page 87 shews that the 12' x 12' section is correct,
7- FORMULAE FOR BENDING MOMENT AND ECCENTRIC LOAD MULTIPLIERS-
(i) Let H ^ Bending momcnt-
F = Bending moment multiplier as tabulated*
M = Section modulus,
I =- Moment of inertia,
g = Kadius of g\TatiQn,
n = Distance from stressed edge to neutral axis,
d = Depth of section,
b = Width of section,
t =5 Web thickncss-
A = Sectional area,
W s= Actual vertical load.
Then the compressive stress due to the vertical load will be
■ ' ^^ •> *•■ •■< ■•• ••* •■* I'j
The additional compressive stress due to the bending moment will be
B -^ M = Ba ^ I = Bn -f- Ag* ... ... (2)
Conseqtiently the total maximum compressive stress will be (W -?- A) + (Bn -=- Ag"), and
the equivalent central load will be this expression multiplied by A, viz.,
■ V -y- X3 . ■>■ ■.. •■• ««■ ,,, '•'J'
t
For all symmetrical sections the value of n will be J-J or Jb as the case may be, so that
the expression . is equal to )d -r g^' and Jb -^ g • respectively.
The valuci of these expressions are the tabulated bending moment multipliers headed
" XX ■' and •' YY " respectively, so that
^\ -= id ^ g/ and F^ = ib ^ g/ (4)
As shewn by equation 3. if the bending moment is due to eccentric loading, the product
B X F added to the actual vertical load W gives the total equivalent central load, as stated
in §6.
(ii) When the eccentric load is transmitted by a girder cleated to the stanchion as in
Fig. 3 or Fig. A, it is usual to measure t as shewn, so that the t>ending moment W x « » |VVd
or JWt as the case may be.
Consequently, the equivalent central load for a flange connection will be
and for a web coaoection will be
W + f|Wd X F,) =W(l +^J
bt
W + (|Wt X F^> - W (1 +-^J
These coefficients of W are the tabulated " Eccentric Load Multipliers.

Notice that iq using the Bending Moment Multipliers, the product of Load and Multiplier
gives the equivalent of the bending moment only; whereas the product of Load and Eccentric
Load Multipher gives the total equivalent central load.
N.B. — The practice of taking r as only Jdor *t tends to underestimate the bending moment.
On the other hand, any error thus involved may be regarded as counterbalanced by the
consideration that, in ordinary building construction, the ends of the stanchions are substan-
tially fixed in position so that the bending moment will decrease from a maximum at the cap
to zero at a point of contraflexure in the stanchion. Hence the corresponding bending stress
at the mid-height of the stanchion, where the liability to failure is greatest, will not be more
than 50% of the maximum,
A more exact procedure would be to take account of the precise mode of connection and
the relative lengths and moments of inertia of the connected members. If the girder is relatively
long and shallow, it will obviously increase the bending moment, especially if rigidly connected
to the stanchion. In such cases, it would be desirable to assign a higher value to *. In cases
where the girder simply rests on a projecting bracket, c should certainly be measured as in
Fig. 5,
8. COMBINATION OF CENTRAL AND ECCENTRIC LOADS-
Fig. 7 illustrates a stanchion carrjnng a central load of 40 tons from an upper stanchion
and unequal loads from girders on all four sides.
The tie beams " A " are supposed to transmit loads of 4 and 7 tons, and the main girders
25 and 30 tons respectively, so that the total actual load is 106 tons,

9. TRANSMISSION OF LOADS TO LOWER STANCHIONS.
(a) The bending stresses set up at th<? junction of girder and staochioQ affect the stressea
ID the stanchion from top to bottom, but those due to loads on one floor tend to neulriili«
those due to tlie loads on the floors above and below. It is, therefore, quite good practice in
selecting a suitable section tor a stanchion, to ignore the ecccntricily of the loads on the
stanchions above it. It follows that, when converting bending moments and eccentric loads
into equivalent central loads, the latter should be &et out separately in the calculations, as
it IS only the actual load on the stanchion above which need be provided (or in the stanchion
below.
{b) Unless there ir^ a reasonable probability of all floors being fully loaded simultaneously,
as in a warehouse, the lower stanchions should not be proportioned to carry the whole of the
calculated live loads o( the upper floors. The provisions of the B S.S. 449, $ 8b, represent
good practice, viz., take the roof and top floor superimposed loads in fulL Take 90% of the
live load of the next floor below, 80% of the next, and so on till fiO% is reached, after which
no further reduction is allowed.
10. WIND LOADS ON STANCHIONS.
In building construction, it is not necessary to provide for more than 75% of the calculated
loads (real and equivalent) due to wind, taken at, say 30 lb- per square foot of exposed vertical
surface. Ihe provisions of the LondoD County Council (and D.S,S. 449) will be found on

11. STANCHIONS BRACED LATERALLY.
(d) Wlien an H stanchion is embedded io a aolid wall in such a way as to prevent it from
bending about the YY axift, a higher load i« permissible, i.^ ., the safe i»trc«s can be calculated
with reference to the Kadius of Gyration about the axis XX.
(A) U'hrn a stanchion is efliciently braced laterally at intervals, so as to prevent it from
bending as a whole, it may be treated as a acriea of independent superimposed ^ ions,
in the case of an ordinary steel-frame building of two or more storeys.
h-
100
NOTES ON STANCHIONS. -Continued,
Id the case of an exposed structure, such bracing ts rarely sufficiently substautijJ to
justify a greater strc^& than that allowed for a btrut with hinged ends.
(c) It a stancliion is thus braced in its weaker direction only, there may be a greater
liability for the stanchion to bend a:^ a whole about it^ XX a?tis than for any of its separate
portions to bend about its VV axis.
12, LATTICED MEMBERS.
For many purposes, highly efficient compresston members are obtained by latticed sections
cOQsisling of a pair of channcU or beams, or of four angles, etc. The lattice bar» are usually flats
or angles at CO* with the axis if single, or 4.5* with the axis if crossed. Their thickness is
usually about l/40th of the length lor single lacing and l/60th for double lacing-
Thc foregoing and other details will be found in § 26 of B.S.S. 44U.
A system of latticing which itself is capable of acting as a strut, independent of the members
it connects {e.g^, double latticing with horizontal members across the diagonals), should be
avoided, as it mav fail under stresses for which it is not intruded, and thereby lead to the
failure of the column as a whole.
13. STANCHION BASES ON REINFORCED CONCRETE FOUNDATIONS.
The commonest form of base is that shewn diagram-
matically in Fig. 8. Gusset plates are riveted to the flanges
of the shaft and the base plate is attached by means of angles.
Rivets are not shewn in the sketch, but botes for the lioldtng
down l>olts referred to in § lo are indicatcd^ I'or stanchions
on reinforced concrete foundations capable of tearing a
maximum safe pressure of bOU \b. per square inch (3^ tons
per square loot approx ^ thcnuvlcof calculation }s as follows :^ —
(a) The rectangular area d x b in Fig, 8 is assumed to
transmit to the shaft an upward toad equal to d x b x 500
Ib^ partly by direct contact and partly by the rivets through
the web of the stanchion.
(b) The remainder of the load is assumefl to be trans*
milted to the shaft by the rivets through its flanges ; and a
sufficient number of rivets, taken at 6 tons per square inch
in single shear, is provided for this,
{c) The projecting portions of the base plate and flange
angles {a in Fig. 8) are assumed to act as cantilevers carr>'mg
a uniformly distributed upward load of such an amount as
will produce a flcxural stress not exceeding 10 tons per square
tDch.
NB, — The rivets attaching the flange angles to the base
ptate are assumed to act merely as connections, and not as
making the angle legs and the base plate act as one solid
plate.

NOTES ON STANCHIONS.— Continued.
{d) The portions of the base plate shoun lightly hatched in Fig- 6 are assumed to transmit
such a pressure as v^ill produce a tlexurat stress equal to that m the projectmg porUous ol the
base, thereby balancing the same.
(e) The areas beneath the edges of gusset plates and under the vertical legs and fillets of
the flange angles, are assumed to transmit an upward load of 500 lb. per square inch through
the rivets to the flanges.
Accordingly, the pressure on the concrete is taken as 500 lb. per square inch over
the areas enumerated in paragraphs (a) and (tf) above; the double-hatched area in Fig. 8
is treated as ineffective ; the pressure under the remaining portions of the base — being limited,
as explained above, by the allowable flexurad stress to the steel — will be Uss than 500 lb.
per square inch.
It is sometimes assumed, for purposes of calculation, that the pressure on the concrete
is distributed uniformly over the whole area of the base plate. This is obviously incorrect,
inasmuch as the deflection of the projecting portions of the plate and angles will relieve the
pressure beneath them in the manner assumed above.
If the load on the stanchion is less than assumed, or the foundations better than
reinforced concrete, the area of the base plate can. of course, be reduced, taking care, however,
that the projecting portions of the steel base are not ovcr-strcssed. For standard riveted and
welded bases, see pages 1 1:1 to 149.
14. STANCHION BABES ON GRILLAGE FOUNDATIONS.
In the ca&e of bases for grillage foundations, the mode of calculation is similar to that
explained in the previous paragraph. That is, a proportion of the total load, represented by
the area b X d in Fig. 8, is considered as passing direct from the shaft to the joi»t(a) directly
below It ; a sufficient number of rivets through the flanges is provided at 8 tons single shear
(or twice this for double shear), to transmit the remainder of the load.
Where a suitable cast-iron webbed base, or plain steel slab, is interposed between the
stanchion and gnllagc joists, as preferred by some engineers, the entire load may be considered
as transmitted by direct conUct, the (unction of the angles riveted to the flanges being partly
to enable the shaft to Im bolted to the baoe and partly in order to approach more nearly to the
condition of " fixed " ends. For further particulars of slab basea, see page l&O.
For notes on the design of Unllage Foundations, see § 19 below.
*
16. OVERTURNING MOMENT IN BASES.
When there is a bending moment in a stanchion shaft there will be a tendency for the
base not to remain horizontal, so that the pressure will not be symmetrically distributed on
the footings and foundations.
II the shaft is not central on the base, or the bue not central on the footings, there will
be the same lurninK tendency, which will increaM with the eccentricity and cause bending
in the shaft ; but a discnmiOD of the treatment in such cases is rather beyond the scope of
this book.
If the bending moment m a stanchion induces tensile stresa» in the shaft, it is necessary
to anchor the base down to the fooUngs by means of holding-down bolts. For method of
calculation, s^e § 22 below.
ie. CONNECTIONS OF BEAMS TO STANCHIONS.
The load from a girder is IranBmitied to a stanchion by direct metal to metal contact,
or by means of a bracket nveted or welded to the stanchioo. In the former case the connacting

angles need not be considered as taking any portion of the vertical load unless the direct
bearing on the stanchion is not sufl&cieat to keep the bearing stresses within safe limits.
17. STANCHION JOINTS.
Joints are usually made in stanchions above the floor level by means of cover plates on
flanges and web. The butting ends should be machined to eniure close bearing, as otherwise
the whole load has to be transmitted through the plates.
An alternative method is to make the joint immediately below the main girders. In this
case, stanchion veb cleats and a cover plate should be used to assist in distributing the load
over the lower shaft. Details of velded and riveted caps, bases and joints will be found on
pages 112 to 149.
18. PRESSURE ON FOUNDATIONS. ^
The allowable pressure on the soil or rock on which foundations rest may vary from 1 to
15 toes per square foot, or even more, according to the nature of the ground.
Those given as a general guide in B.S.S. 449 will be found on page 285, and accord with
average practice.
If the footings are not large enough sufficiently to distribute the pressure, the bearing arcft
may be increased by a steel joist grillage (see below), by a stone slab, or by a concrete base,
plain or reinforced,
19. STEEL GRIULAGES.
(i) These consist usually of two or three tiers of joists crossing one another at right angles,
and should be designed as follows : —
Id figure 9 below, if 2* is the width of the wall or stanchion base, the projecting
lengths a are assumed to act as cantilevers carr>Hng a uniformly distributed upward load, and
the length of joist V> is assumed to be uniformly loaded by the difierence between the loads
from above and below.
The load, shear and bending moment diagrams are, therefore, as illustrated in Fig. 9.

Tlie length 2b may be taken as the overall width of a cast iroo base or as the distaoce
between the outer rows of rivet holes in the case of a riveted steel base. For the lower tiera,
23 may be taken as the distance between the centres of the oatside joists of the tier above.
(ii> The web of the grillage joist has to act as a colomn, and the direct stress sbookt not be
greater than the safe stress for a strut with £xed ends of which the l/g equals V ^^ ^ ^^ °^^
depth of the web -=- web thickness. (These stresses are tabulated ior ordinary joists in the
colomn headed P^ on page 175. acd for Broad Flange Beams on page 38,) The prcssiue majr
be taken as dlstnbnted o\-er an additional length of web equal to 3/14>ths of the depth of the
joist on each side of the load. This aspect is dealt with more folly in the notes on Stresses in
Girders fsee page 62, f 4),
(iii) The London Coanty Council By-Laws (and B S S. 449) allow the stwsses in grillage
beams to exceed the ordinary working stresses by 50%, subject to the beams heing adequately
embedded in concrete ; see page 282.
To prevent - - of the joists, thej' should have a covering of concrete at least 3'
thick, and to enable tiie concrete to be well rammed, a space at least 3' wide ^konld be left
between the flanges in each Layer.
The top layer of joists should be as close as practicable, to get the requisite web area to
icsUi the shear ; the lower layers may be spaced at say 12* to 18' centres.
The joists should be tied together by rods to prevent them spreading during tamping
and spaced by tubular distance pieces, unless separators are required to stiffen the webs.
The projections of the joists should cot esceed about 3 to 4 times their deptii.
Tbe base of the stanchion should be bolted to the top flanges of the fiiyt lavcr, which in
tnm should be connected to the layer below, but no deductions need be made for bolt holes if
the foregoing method of calculation is emploj-ed-
It is ad\-isable to bed the bottom layer of joists on steel bearing plates to facilitate the
mo^-ing and wedging up ot the grillage aa a whole when plumbing and leveliing the stanchioas
and &rst floor bcam^.
It is well to wedge up the ends of the bottom layer of joists, and not to fill in with concrete
till a considerable load is on them, as the deflection induced will help to distribute the toad
more uniformly on the cc^npleted grillage.
20- STONE AND CONCRETE FOUNDATIONS,
Other forms o£ distributing media may be designed as cantilevers on the same principles
as employed for the design of bearing plates. (See page 57, § 11.)
The safe stresses in stooework may be taken as there tabolated.
For reinforced concrete 1:2:4. composed of proper materials and well mixed, an extreme
flexural compressive suess ot 600 lb, per 5<juarc inch is permissible.
For permissible pressures on concrete footings, see page S85 iB.S.S. 449. § F),
21. HOLDING<DOWN BOLTS.
When there is no tendency for the stamJuoo base to overturn, boldine-down boits are
occastoaally omitted ; but this is oot good practice, and it is certainly desirable, espcctaJly
during erection, alwavs to secure the stanchioo bases to the foundation blocks by means o(
holding-down bc^ts. Holes for these should be left in the foondation bJocks, of such a diameter
as to allow the steelwork erector a small margin for adjustment »hen Uning and plumbinc the
stanchions, after which the voids must, of coarse, be filled up with Uqmd cement,

NOTES ON STANCHIONS.— Continued.
22. DIAMETER OF HOLDING-DOWN BOLTS-
If there is bending moment inducing tensile stresses in the shaft at tlie base, the requisite
diameter of the bolts can be ascertained as follows : —
If B = the total bending moment (inch-tons),
C = the distance (inches) centre to centre of the bolts in the direction of
overturning.
W = central load on the stanchion (tons),
then (B -^- C) — (W -^ 2) is the commonly assumed value of the tension (tons)
to be taken up by the bolts on the tensile side of the stanchion. This value, however, is too low,
as the centre of compression '*vill be nearer the centre of the shaft than the holding-down bolts
For this reason the working stress on the bolts should be reduced to 6 tons per square inch
for steel,
S3. WIND BRACING.
A good system of heavy bracing, composed of angles riveted to flame-cut pieces of the
same section as the main girder, is shown in Fig, 10 : the girder in this example is one of the
larger sizes of Broad Flange Beams. A less efficient method, but suitable for medium loads and
occupying a minimum of space^ is shown in Fig. lU the tees being cut from R S. Joists,

WEIGHTS OF CONNECTIONS.
The statud weights allow for rivet heads but not for field rivets or bolts, nor for
bol ding-do v^Ti bolts.
CAPS-
The stated shear values of the ri\"ets are based on fi tons per sq, in. single shear ;
the thitkutsses of the angles are sufficient to give a bearing value of not less than
12 tons pLT sq. in. The choice between the " ht'a\'y " and " light " types uill depend
of course on the si^e and capacity of the gird^s to be supported.
M'ith IV and 12" rtaug«, double rows oi bolts and nvets may be used, thereby
dispensing with the gusseted brackets usually required with built-up stanchions.
Sec pages 127 to 12fl.
SLEEVE JOINTS.
These are designed to suit stanchions of the same nominal section, but of the
Die and Dik weights respeclixely. Sufficient rivets at 6 tons single shear, or twice
this amount in double shear, are provided to transmit 60% of the safe loads Ubulated
on pages 84-91 for the minimum weight and a height of 12 feet,
[When the two stanchions are of different sections, such joinis must be ajranged
in the manner shown on page 107.]
BASES.
As indicated in the notes to the various drawings, it may in some cates be
necessar)- to distribute the load over a greater area of the foundation, by means of

grillage joists for example, [tor notes on the design of grillage foundations, see
page 103,]
The " alternative " bases shown {for sections up to 1" x 7") are to be preferred
for small and urgent orders, being designed to suit stock sizes of angles.
The reinforced concrete foundations are assumed to be capable of bearing a
pressure of 500 lb. per sq. in. {32 tons per sq. ft, approx,). The assumed load on the
stanchion is the safe central load for a stanchion 12 feet high as tabulated on pages
84-91 [B.S.S. formula, hinged ends, mild steel),
PRINCIPLES OF DESIGN.
The bases conform ^vith the general principles already indicated on page 101
namely : —
(o) The area d x b in the annexed illustration is assumed, to transmit its share
of the up-ward load to the shaft partly by direct contact and partly by the rivets through
the web of the stanchion,
[b) A sufficient number of rivets through the flanges are provided at 6 tons
single shear (or twice this for double shear), to transmit the remainder of the load.
[c) The projecting portions 'a' of the base plate
and flange angles are assumed to act as cantilevers
carrying a uniformly distributed upward load of such
an amount as will produce a flexural stress not
exceeding 10 tons per sq, in,
[d) The portions of the base plate shown lightly
liatched are assumed to transmit such a pressure as will
produce a flexural stress equal to that in the projecting
portions of the base, thereby balancing the same.
{e) The double-hatched area is treated as
inefEective,

WEIGHTS.
The stated weights allow for the fillet welds shown.
CAPS.
The cap plates are shown with the minimum projection (J") required lor the
welding operation. Usually, no greater projection will be required, connection bolts
to the supportfd gir(ler(s) being located between the stanchion flanges ; but the
plates can he extended when necessar>', eg., to provide a longer bearing for girders
hshplated over the sUnchion. The unstiflened plates are welded along the stanchion
web and outside flange edges only.
STANCHION JOINTS.
The type of joint shown for the various stclions is more economical than the
splice plates customary jn riveted joints.
For the purposes of the drawings of Din sections {ripht-hand pages), the upper
stanchion is assumed tn be the Die (minimum) weight of the same section. In these
and aU other tascs where the whole section of the upper stanchion has a direct bearing
on the stanchion below, a sufficient thickness for the division plate is 3/8' for sections
up to 7 . 1/2* lor sections 8* to 12', and 6/8' for sections 14' to 18'.
In these Din <Ira«-ings, the sizes of the welds on the division plate have been
made siifhcient to yield not less than 60% of the moment of resistance of the lower
stanchion.
In the drawings for Die sections {left-hand pages), the upper sUnchion is assumed
to be a smaller Die section (shown in the table below). In these cases, the thi(-kncss of
the divi sion p late ha.-i been made sufficient to transmit the load on the assumption
1 *. that the upper stanchion is stressed to 4) tons per sq. inch, allowing
J ^ a flexural stress in the plate not exceeding 8 tons i>cr square inch.
( ( The required thickness (p) of the division plate will vary
_J 1^ according to the length ol the lever arm a in sketch and the load on
p the upper stanchion. Assuming the compressive stress in the upper
-| j~ stonchion flange to be 4| tons per square inch, then the necetsar>'
thickness of the division plate, allowing a flcxtiral stress in the plate
not exceeding 8 tons per square inch, max- be found by the formula

If the size oi the upper stanchioa is such tbat it has very nearly but not quite a
complete direct bearing, an intermediate thickness for the bearing plate will bo
suitable.
For the sake of the fillet weld, the division plate must have a projection of not
less than 1/2", as shown on the draAvings.
The web cleats provided serve only for bolting the stanchions together during
erection ; they are made small, usually only 3" x 3", so as to leave room for the
welding between the cap plate and stanchion shaft. These angles are \\elded along
the two vertical edges to the upper stanchion web, and along the outside edge to the
division plate.*
SPLICE PLATES.
If the use of splice plates is preferred, as in Figs, 1 and 2 overleaf, the appropriate
size of splice plates may be ascertained from the following table: —

Id recent steclframe buildings ia EDglandand the United States^slabbasesare widely used
in preference to riveted bases ; slab bases are made with steel plates thick enough to permit of
the entire load being transmitted from the column shaft to the base plate by direct contact. The
primary object is to avoid loss of space in the basement, or the alternative of deeper excavation.
Unless the stanchion load is very great, slab bases can be made large enough to go direct on to a
concrete or reinforced concrete foundation, thereby dispensing with grillage joists. This t>T>e of
baseisnot appropriate for exposed work. eg. sheds, tank supports, viaducts, etc. v here there is
an overturning moment to be taken into account, unless the structure is efficiently braced to
prevent raking.
Fig. i;
If the stanchion is placed direct on the concrete foundation, the area of the base is deter-
mined by the allowable pressure (P) on the concrete. This is usually taken at figures ranging
from 30 to 40 tons per sq. foot.*
For Mcertaining the required thickness (t) of the slab, t\\'o formula are in vogue, giving
rather widely different results,
(i) That given in British Standard Specification 449. §25a. is equivalent to: —
t^=3p/f(y--Jy,»).
where p = safe pressure in tons per sq. inch,
f = safe tensile stress in the steel, taken as 9 tons for mild steel or 13*5 tons per sq.
inch for high tensile steel,
y, y\ = projections of slab, as in fig. 1, y being the greater.
This formula treats the projecting portion of the slab as a cantilever of lengthy, with an upward
load of p per sq inch over the area B y, and takes into account the counter-effect of the trans-
verse strain, Poisson's ratio being taken as one-fourth.
(ii) The more conservative and theoretically less correct formula adopted in the London
County Council's By-laws, 1937 (§69) is equivalent to : —
-=^i(^^)
where (D — d) is the greater overhang,!
W = total axial load in tons.
f = safe tensile stress, taken as 9 tons per sq. inch, asbetoe.
This formula assumes the maximum bending moment to be at the centre of the slab treating
it in effect as a pair of cantilevers of span B 2 with an upward load W/ 2 distributed over B; 2 and
an equal downw ard load distributed over b/2.
In the table on page 151, appropriate dimensions of mild steel bases are given for both
formulae, and for alternative bearing pressures of 40, 35 and 35, 30 tons pcrsq, foot.

SLAB BASES— Continued.
8LAB BASES ON QRILLAQES.
The thicknesses ol slab bases on grillages are calculated in a similar manner.
The breadth of the plate is determined bv' the size and number of RS J. 's beneath, sufficient
space being left between the tlanges for concreting in.
The depth of the plate is arranged so that the overhang is not so great as to necessitate an
uneconomical base. •
MACHINING,
In American practice, slabs up to 2' thick are rolled flat and smooth enough to be used
without further treatment. Plates over 2' to 4' thick are straightened in a press ; with plates
over 4' thick, theareaincontactwith the column shaft and its angles is machined ; if a slab over
4' thick rests on grillage joists, the underside also of the slab is machined In British practice,
the area in contact with the column shaft and its angles is usually machined ; the underside also
if the slab rests on grillage joists.
COMMERCIAL THICKNESSES
The thicknesses of slab bases as ordered from the mills are usually round figures to the
nearest fourth of an inch up to IJ* ; over 1^', to the nearest half-inch. About J' must be allowed
for machining ; or J' if both surfaces are to be planed.

This table is to be read in conjunction xsith Figs. S— 1. The tabulated weights include the
cleats, rivet beads, and bolts (countersunk on underside] sboun in Tigs 2-4. All rivets and
bolts are j[' diameter.
In computing these ^vcights, the thickness of the slab is asttumcd to be the nearest round
figure (in fourths of an inch) above the theoretical thickness as given in Table A, except those
marked with an asteritk, for which the theoretical thickness is less than 1/10" above the
nearest round figure; in these cases the neatest round figure is assumed. Sec also notes on

BROAD FLANGE BEAMS, GREY PROCESS^
AS POLES AND STANDARDS.
Broad Flange Beams. Grey Process, are ver\' suitable for electric power, telegraph,
and telephone poles, railway signals, lamp standards, tram and trolley-bus standards,
and railway electrification, and are extensively employed for these purposes. A t>'pical
electric railway portal structure is illustrated on page 160, and various simple connec-
tions for standards on pages 162 to 164,
Comparison with other types of poles — reinforced concrete, timber, and steel
(latticed or tubular) — shows the superiority of the wide-flanged steel beams ^^-ithin
the limits of their capacity.
The ordinarj' rolled steel joist is unsuitable owing to its relatively narrow flanges,
and consequent weakness about the YY axis. Broad Flange Beams, Grey Process, are
usually adequate in this respect ; but where necessary, the various sections from 4'
to 8" can be supplied with extra wide flanges (see table on page 164),
Though heavier than tubular or latticed poles, B.F, Beams are cheaper, owing
to the higher price of tubes, and the fabricating costs of latticed poles. The economy
of the B.F, Beams is still greater in the long run, owing to their longer life, as they are
easily painted all over, and the metal is thicker.
They can be delivered with the utmost speed, owing to the very little work to be
done on them after rolling, and they can be roiled at the rate of 500 to 1,000 tons
a day.
They occupy less ground space than latticed poles — an important consideration in
large towTis ; and owing to their square shape and clean square edges, they are in fact
less unsightly than round jxjles. The ends can readily be shaped in the manner shown
on pages 163 and 164, Figs. / and t\
Their wide parallel flanges ofier the utmost facility for all requisite connections;
and unlike tubular and concrete poles, they are easily climbed by means of simple
climbing irons of special form.
The fact that these l>cams are of uniform section, instead of tapering towards
the top. means surplus material ; this, as pointed out above, is more than
compensated for by the low cost per ton. But if preferred (on the score of appearance),
poles can be made ^^ ith Broad Flange Beams of diminishing section, by the Acma
system, as illustrated on page 161.
These beams can be rolled in any lengths required. Lengths up to about 40 feet
can be galvanized, if required ; but this adds considerably to the cost. At far less
cost, they can be rendered partially immune to corrosion by a small addition of
copper (see "Tests, Extras").

TAOt-E B. The alternative Tabic H (page 157) is designed to conform with the
tk-ctritity Commissioners' Overhead Line Kegulations. Accordingly the wind
pressure is taken as H lb. per wj. foot, and the total stress limited to two-hlths of the
calculated clastic limit of ITi-tl tons i)er wj. inch (60% o( an assumed ultimate tensile
strength of 2() tons per wj. inch nummum).
by this lorniuU. we have P = 1167 Z,/L- -I lih.
QUAHTV OF 8TCCL.
Ihe tabulated safe loads arc appropriate to uur " Standard " quality of steel viz
26 tons minimum tensile (sec page 267).
1- v-,"J''^ British Standard grade is employed (28/33 tons tensile), the loads in
I able B can be increased by one-thirteentii.
DEFLECTION.
tn each table. loads to the right of the zig-zag line, when combined wah the
specified wmd pressure (25 and 8 lb, respectively) produce a deflection exceeding
1/4 per foot of height, which in some cases may be objtxtionable- The .:
corresponding to any given load can be ascertained bv reference to the .. :,
tables on pages 158, I5». These tables arc calculated by the usual f.jrmula? and
assume an elastic modulus of 13,000 tons jut s<j inch.
DIMENSIONS
The sizes given in these two tables arc the ' nominal * sizes ; for the ' exact '
dimensions, see table on pages 16~2u.
WEIOHTQ.
Safe loads arc given in these tables for sections up to 12' -^ 12' in each of the
three weights which can be supplied uithout limitation as to quantity, viz.:
The Die (minimum) weighu, mailced f m the tables
the DiL (reduced web) .. „ /
the Di.N (medium) ,, .. » "' \\
The niE weights will usually be found the most advantageous. As may be
seen from the table on pages 16-20, ail of these sections can, when re»iuiretl. be rolled
either to greater weights or to intermediate weights, subject to the conditions as to
minmium tonnage specified on page 286.

B.F. BEAMS AS PILES.
Broad Flange Beams, Grey Process, have been used extensively as piles ; notably
in England, Hongkong, Shanghai, and Karachi- A large tonnage of the 12' Die
section vas recently shipped to Shanghai in unjointed lengths up to 105 feet : the beams
fulfilled the dual purpose of piles and superstructure legs in a large jetty. In case of
need, to facilitate transport, the beams can be spliced as shewn on page 166, or velded
together at site.
In 1936, some 1,600 tons of 12' Din ^vere used as foundation piles for a slipway
in a large North of England shipbuilding yard in lengths of 60 to 75 feet. Other
frequent uses of these beams as piles have been fur riverside 'uhanes, warehouses,
embankment strengthening, and king piles.
They can be pointed when necessary* in the various ways shown in Figs, 1 to 3
below- The points shown in Figs. 1 and 2 cost about 6 to 8 shillings each. In Fig. 3
parts of the web are cut away by oxy-acetylcne. the flanges bent over hot, anti the tip
arc-welded at a cost of about 10 to 12 shillings per point-

Compared with concrete piles, steel beams have many advantages. They can
be rolled at the rate of 1,000 tons a day in the lengths and section required ; and
they can be driven and top work continued with a minimum of delay. The most
simple dri\ ing equipment is usually sufficient, and with steel the risk of head or point
shattering or undetected fracture under driving impact is almost excluded. Further,
the inherent strength of the steel section often obviates the necessity of soil boring,
with its attendant expense of time and equipment. The liability to deterioration in
sea water or chemical-laden soils is possibly greater for concrete than for steeb

The piles illustrated above are of B F. Beams, Grey Process. 12' x 12' x 81 lb., as used in
aQ extension to the Hong Kong & Kowloon Wharf,
The splicing is only required for convenience of shipment, as these beams can be rolled in
lengths of 100 feet and more (seep. 287) and have in fact been shipped m lengths up to 1U5 ieei.

SHEET PILING.
Steel Sheet piling, consisting of interlocking sections, is widely used for constructing
coffer dams, retaining walls in docks and harbours, quays and wharves, river protection and
sea defence ^'orks, etc.
In the Larssen system here illustrated, comers are formed by bending one of the standard
sections as in Figs. 1 to 3, or by the addition of angles as in Fig. 4. Junctions are made with
the aid of a half pile {spUt vertically down the centre) and with an angle added, as in Fig. 5,
for example. The box pile sho\^ n in Fig. G is composed of tw o Larssen sections welded together :
this t>'pe may be used in lieu of pre-cast concrete or timber piles.

For permanent work, the steel should be coated w-ith neutralized tar or other appropriate
anti-corrosion composition before driving- The web thicknesses of certain of the sections can
be increased if desired and if the required tonnage is sufficient to warrant it.
The Larssen piling is usually suppUed in the ordinary British Standard grade (28/33 ton&
tensile), with or without copper. It can also be supplied in a rust- resisting steel of 36/40 tons
tensile.
There is sufTicient play in the interlock* to permit of the piUng being driven to a fairly small
radius — e.g., sections up to No. 3 can be driven at an angle up to about 9*, enabling a complete
circle to be formed with a minimum of about 40 piles ; with the larger sections, the maximum
angle is about 7*, and the minimum number to a circle would be 40 to 50, These sections have
been rolled in lengths up to loo feet.
The sheet piling may be left in position, withdrawn after use or cut off at or below the
water-line by oxy-acct^icne or oxy-hydrogcn flame (if below the water-line).

4 SENDING MOMENT
MULTIPLIERS. To obtain the equivalent central load producing tl
e same
eoaipressivc stress as that
due to bending about the XX axis, multiply Uic bending moment (int
Ji'tons)
by the tabulated multip
Jer. Wben the horizontal leg is in compression, use the multiplier
b traded
"Tabic"; for the verUc
al leg ID compression, use the muIlipUcr headed " Stem." The result
, aiidcd
to the actual vertical toat
i, must not exceed the Ubulatcd safe load. It the bending is about
the YY
axis for a pair of angles
the value 6( the multiplier is the horizontal breadth - ^By»- For

The above diagram gives the normal component on a sloping surface, due to a horizoa^al
wind pressure of 30 lb. per square foot reduced in accordance with Duchemin's formula : —
Normal Pressure — Horizontal Pressure x 2 Sin a ^ {I + Sin* a) where Sin a is
the ratio of rise to length of slope.
The vertical and horizontal components of thJa normal pressure can be scaled from
the diagram.
The pressure in lb- per Square foot = Square of Wind Wlocity in miles per hour^

The above are the rough estimated weights per square foot of roof surface, t^ . measured on
the slope if sloping. For wind loads, see page 218, For weights of various other
substances, see pages 306-307,
WEIGHT OF TRUSS. This will usually not exceed I lb. per square foot of actual roof
surface for each lO feet of span, i.e., 3 lb, per square foot for a 30' 0' spaa, and so on. The
assumed weight should be verified after design.
flOOF DRAINAGE. British practice is to place down pipes at centres not greater than 20 feet,
and to provide an internal area not less than I square inch per 60 square feet of surface drained.
Gutters should have a width not less than twice the internal diameter of the down pipes
and a fall of about ^\' in n feet, where n is the gutter width in inches. For pressed steel
gutters, see page 224,
ANGLES AND TEES, For their weights per foot, and for the &afe loads of angles as struts, see
separate chapter hereon, pages 191-205.

NOTES.
1. Gauge, The thickness is generally expressed in Birmingham gauge, and is understood
to refer to the thickness before galvanising. The thicknesses obtainable range from 12 to
30 B,G. The thickness most commonly used is 24 E.G. ; but for first-class roofwork 18 and
20 B-G. are commonly specified.
2. Stocks. The sheets most commonly stocked are of lengths 5, 6, 7, 8, 9 and 10 ft, : width
8/3' corrugations ; thicknesses 20, 22, 24 and 26 B,G.
3. Corrugations. The commonest pitch {c in above sketch) is 3' and the depth usually
one-fourth of this ; 16 and 18 B.G. sheets are usually made with 5' corrugations ; 4" and other
corrugations are also made. For corrugations of the proportions sheun in the sketch, the
area of the sheet before corrugation is 1 ■ 16 times the area covered,
4* Spelter. In first-class ^vork the amount of zinc called ioi is usually 2} oz. minimum
per sq. ft. There are also chemical tests.
6- Strength, \\ ilh the configuration shewn, the section modulus for 1 complete corrugation
is '077 c'/, where t is the thickness in inches and c is the length of the corrugation. The
breaking stress may be taken as about 18 to 20 tons per square inch,
6. Side Overlap. The minimum side overlap (" one corrugation overlap ") is 2'- For one
complete corrugation overlap (" two corrugations overlap "), it is 5".
7, End Overlap. In a roof, this should not be less than 6', but in vertical work it may be 3*.
8< Rivets and Bolts. Rivets will weigh about 3 Ib^ per 100 feet super; hook bolts and
washers about 4 lb. For details, see opposite page-

STEEL BEAMS IN CONCRETE.
1. TABLES,
The Tables below will be found useful for determining the appropriate section anJ spacing
of " filler " joists embedded ia concrete. The procedure is to ascertain the Bending Moment
from Table A and then to select from Table B one or other of the arrangements wluuh provide
a corresponding Moment of Resistance.*
2. EXAMPLE.
A factor^' floor is to be constructed with concrete and R.S. Joists supported on main
girders spaced 11 feet apart, centre to centre, to take a superimposed load of IjD tb- per
square foot. If the thickness of the concrete has not already been determined, the dead
weight must be provisionally estimated, with due allowance for floor linJsh and ceiling.
Table C may assist in this. Supposing it to be 74 lb. per square foot, then the total floor
load will be 150 + 74 = 224 lb, per square foot.
Takiing the span of the filler joists as equal to the spacing of the main girders, namely
11 feetf. reference to Table A shews that the corresponding Bending Moment (per foot of
width) is 18'1 ton-inches.
Now, turning to Table B we find that we could use 5' X 3' ]o!sts with 1' top cover at
3' 6' centres, and that there are various other possible arrangements which ^^ill give the
required moment of resistance — eg., 4J' X 1 J' joists with 2' top cover at 2' 5" centres.
To accord with the recommendations of British Standard Specification 449 (§ 14), the
span of the flooring must not exceed the maxima given in Table B,
3. ALTERNATIVE tOADS.
The ordinan^ allowance for floor loads may not make adequate provision for concentrated
or unequal loading. In order to provide for such conditions, British Standard Specification 449
(5 8a) and the London By-laws (§ 4) prescribe that beams and slabs respectix'ely must be capable
ofcarrj'ing alternatively (i^., with an otherwise unloaded floor) the superimposed loads tabulated
in column B on page 280.
Thus, in the example cited above, each reinforced filler joist (or where the spacing is 3' or
less, each pair of joists) must be capable of bearing a superimposed distributed load of 2 tons.
With 5' X 3'joistsof l]'spanat3'6'centTes, thisisequivalentto4,480-h (11 x 3-5) = 117 lb.
per sq, foot. With 43' joists at 2' 5' centres, a distributed toad of 1 ton per joist (2 tons per pair)
is equivalent to 85 lb. per sq. ft. In either case, as we have assumed a superimposed load of
150 lb. per sq, ft., the alternative loading is amply provided for.
Kegawiing the whole flooring system from main girder to main girder as a " slab/' it
must be capable of sustaining a superimposed load of | ton (S40 lb.) per foot of width ; and
we have in fact provided for a superimposed load of 11 x 150 = 1,650 lb, per foot of width.
• It win t# swti that in Table B the Resistance Moments are calculated lor each joist section f^r a cover of one
inch and l^*'o inches oi concrete, respectively. The Resistance Moments for the same R.S. Joists with either moie or
IfSS cover of con^ete caii readily be ascertained by extrapoLitioa, with sufficieat accuracy for practicsU p-urposes ; the
error wiU be oa the Sale side.

4. MAXIMUM SPACING.
To avoid excessive tensile stress in the concrete between the joists, the ratio of span to
depth— i.rf., the ratio of the spacing of the joists to the thickness of the concrete — must uot
exceed the following unless the concrete between the joists is reinforced (e.g.. by expanded
metal) or the joists prevented, by tie-rods or otherwise, from spreading : —

The foregoing ratios are calculated by the usual formula, treating the concrete slab as a
beam freely supported at both ends, and correspond to tensUe stresses of 30 and 60 lb per
square inch respectively.
For example, if the toul floor load is 200 lb. per foot super and the (total) thickness of
the concrete is 6 inches, the maximum spacing of the joists for poor unreiaforced concrete
will be 5 -4 X 6 = 32 -4 inches, say 2' 8'. or for first-class concrete 7-6x6= 45-6 inches,
5-EV J y ,
N.B.— The British Standard Specification 449 gives a more rough-and-ready solution
putting the maximum ratio as six times the thickness of the concrete, unless " suitable transverse
reinforcement " is provided (irrespective of the floor load).
6. WORKING STRESSES. (For War Emergency stresses, see page 6.)
Table B is designed to conform with 5 12 of British Standard Specification 449, which
permits of a working stress in filler joists of » tons per square inch.* Figures to the left of
the hea\y line are determined, however, by the safe compressive stress in the concrete {taken
as one-fifteenth of 5 tons. viz.. 750 lb. per square inch approx.) ; except that where this limitation
would give a lower value than for the unrcmforccd joists with a working stress of 9 + / tons
per square inch, the latter values are given instead, in italics.
B.S.S. 449 allows a working stress of 9 + ( tons per sq. in. up to a maximum of 12 tons
per s(|. in. ((or high tensile steel. 13 -f- IJ f up to a maximum of 10^ tons per sq. in.), t being
the thickness in inches of the concrete above the upper flange of the joist.
6. GENERAL PRINCIPLES.
The principles on which Table B is founded are equally applicable to other arrangements
of beams m concrete, e.g.. railway bridges composed of Broad Flange Beams in concrete.
The tensile strength of the concrete is neglected and all the tension is considered as taken
by the steel.
It is assumed that when the composite beam is deflected under the load, the alteration
m lengrth of the concrete is the same as that of the steei. As the elastic modulus of steel is
about 15 times that of the concrete, the stresses in the steel must be 15 times the stresses in the
concrete. Thus, if the concrete is stressed to 600t lb. per square inch, the steel in contact with
It wUi be stressed to 4 tons per square inch.
In calculating the strength of such a beam, it can be treated as consisting entirely of
steel, but vnth the area of the concrete divided by 16* and all the concrete below the neutral
axis omitted.

JOISTS IN CONCRETE.— Continued.
The neutral axis will pass through the centre of gravity
of this equivalent section and the moment of inertia and
section modulus can be calculated in the usual way.
If d = depth of the steel joist {see Fig, 1),
A = its area,
I = its moment of inertia,
M = its section modulus^
l> = depth ol the composite beam measured from
underside of joist,
b = breadth of the composite beam.
n = distance of neutral axis from top of composite beam,
Mc= compression section modulus of the composite beam,
Mt = tension section modulus of the composite beam.

Re = resistance moment of composite beam when concrete is fully stressed.

Rt = resistance moment of composite beam when steel is fully stressed in tension,
t ^ working tensile stress in the steel (9 tons per square inch in the table on page 229),
Then Rc= Mc x c in ton-inches, if all the length units are expressed m inches,
and Rt = Mt x t in ton-inches, if all the length units are expressed m inches.

It is the value of He or Rt. whichever is the smaller, in ton-inches for various values of

that the value of b is taken as the distance between the joists, centre to centre.

V
In ver>- heavy work, butt welds of J. U and double U tvpes are also employed
on occasion ; but are preferably avoided owing to the higher "cost of the preparatory
machining.
The " single " types should have a reinforcing run along the back ; when this is
impossible the normal working stress should be reduced by one-half, unless another
part is in contact with the back of the vee, the plates are bevelled to an edge, and fusion
IS ensured both in the bottom of the vee and witli the backing plate by making the
first run with an electrode not larger than 8 SAV.C. (L.C.C. § 17).
The reinforcing run or runs should amount to 1/IOth of the platc Uiickness ;
they may be ground off afterwards \vithout reducing the working stress.
TJie working stress in bevel (and Jl joints should not exceed 3/4ths of the
normal (L.C.C. § 8).
FILLET WELDS
These transmit longitudinal shear or transverse shear or a combination of the
t«*o. andmay be " end welds" or " side welds." Both are illustrated in Fig, 7 overleaf.
234
METAL ARC WELDING.— Continued.
Transverse Shear
Fig. 7.
In end ^velds, the line of weld is across the lines of stress. In side welds, the line of
weld is along the lines of stress, and the weld tends to fail in shear along the plane
of the throat. It is usual now to make fillet welds with the legs equal, and with the
surface slightly convex.
Most authorities regard welds transverse to the direction of stress as the more
efficient.
The size of a fillet weld should be specified hy the length of the shorter leg, the
throat thickness being not less than 0'i07 of this (B,S,S., page 8), Accordingly,
thestrengthof the weld is to be calculated on 7 /lOths of the'' size." Its effective length
should be taken as the actual length minus twice the " size " (L.CC, 21) ; but where
end fillets are returned as side fillets for at least I inch, the full length of the end fillet
can be deemed effective (L.C-C 41), In certain Continental and Indian specifications
it is the throat thickness which is taken as the " size."
WORKING STRESSES
The L.CC. allows, in tension and compression, 8 tons per square inch. In shear :
in web5 of plate girders and joists, G tons per square inch; otherwise 5 tons per
square inch. The table on page 237 is based on these stresses.
In Fillet wetds, the B.S,S. and L.CC. both allow for end fillets 6 tons per
square inch, for side fillets 5 tons per square inch ; calculated in either case on the
sectional area at the throat (i.e. 0-7 of " size " multiplied by the effective length).
The allowable stress for end fillets is 7 tons per square inch, as in the table of safe loads
on page 239.
ELECTRODES
Suitable sizes of electrodes, according to the thickness of the plate and the space
to be filled, are indicated in the tables on pages 237 and 239. These and the stated
currents may have to be varied^ however, to suit different makes of electrode. The
choice of gauge will depend also on the welding position. A variety of grades are
employed according to the character of the work, composition of the parent metal, etc.

COST.
Welding costs can be estimated approximately from the data included in the
tables on pages 237 and 239. These show, per foot of weld, (i) electrode consumption,
(ii) current consumption, and (iii) average time taken in practice by experienced
operators.
The stated consumptions of current assume general purpose electrodes and an arc
of 20 to 23 volts. The stated times represent the " net " estimated time required to
deposit the run, change electrodes, and remove slag.
The actual time taken in practice \\4I1 be IJ to 4 times the tabulated figures, or
even more, according to the class of work and organisation of the shop-
TESTS.
The ^arious methods employed for ensuring the quality of welded work are as
follows : —
(i) Inspection of welds after each run. On important work X-rav or Gamma ray
examination is also used,
(ii) Periodic testing of operators, usually at regular inten-als by the works
management. The usual tests are bend tests on butt welds and inspection tests on
fillet welds. For the latter a single fillet weld between t\\'D plates at right angles is
broken for examination,
(iii) Electrodes are tested by bending, tensile, and Izod tests on all weld-metal
test pieces. Tensile tests on butt and fillet welds are made for a specified quantity
of electrodes supphed ; see for example B.S,S. 639, 1935 (§ 8).
On all weld-metal tests, covered alloy electrodes of the best makes (for structural
work) usually give such results as ; —
Tensile 28/33 tons, Yield Point 21/25 tons. Elonpation 15/25% on
8 diameter?. I/od 40 GO ft. lb. The minima required by B.S.S. 538/1934 were :—
28 tons per :>quare inch tensile, 20% elongation on 3' 64 diameters, 3U It. lb. Izod.
DESIGN.
(i) Joints should be so designed that the stresses in the welds are readily
determined — Imtt welds in direct tension or compression and fillet welds in end shear
and side shear, \Vhen stresses cannot be so resolved, special tests on the type of
joint should be made. Welds shcmld be so arranged that there are no bending or
tAvisting moments about their longitudinal axes, XX in Fig. 8.

(ii) \Mien stress is transmitted through a ueld to parts of a member of varj'ing
rigidit5^ stiffening pieces should be used to transmit the stress from the flexible to
the rigid parts of the member. Compare Figs. 9 and 10.
Fig. 9.
Fig. 10.
(iii) In butt welds concentration of stress is liable to occur at the ends, ow-ing
to the difficulty of finishing the ends symmetrically. It may be necessary therefore
to form pads of weld metal across the ends of the beads.
F»8.1L
In any case, a piece of plate, or continuation pieces to ^ve the shape of the vee.
should be held or clamped to the edges of the parts being butted, as in Fig. 1 1 , to
enable the arc to be continued right up to the edge without crater formation ; these
plates can readily be knocked oflf after the operation.
(iv) Floor beam^ may be made continuous by making connections capable of
resisting the full negative moment at the supports. Where there is longitudinal
restraint of the members connected. co\er straps or other reinforcement of the joint
should be added, sufficient to develop at least 25% of the strength of the flange in
tension. Or a beam may be made continuous by cutting through the supporting
member and making any necessary splice joints at the points of contraflexure.
Where continuity is not required, the beam should be freely supported by angle
cleats or other means which will allow free deflection of the beam ; and welds should
be so placed as to reduce to a minimum secondary bending stresses in beam and welds.
(v) Column joints should be machined square and have sufllicient welding to

transmit all forces other than wholly compressive forces. 11 there are no other forces,
sufficient welding for erection and location purposes (compare B.S.S. page 23 §o, L.C.C.
§48),
(vi) In lap joints between plates, the lap should be at least four times the thickness
of the thinner plate (B.S.S, page 23 § j, L,C,C. § 42).
(\'ii) The effective length of a fillet weld to transmit loading should not be less
than 2* nor less than six times the size of the weld (L.CX. § 22),
(viii) Contact surfaces exceeding J' in width exposed to the weather should be
sealed against ingress of water (Cf., L.C.C. § 36),
(ix) Welds used for connectiuK bracing members should be designed to develop
the lull strength of the nuinbcr (B.S,S. page 22 § e, L.C,C. 4 35).
(x) Slots should not be filled with weld metal, and their width should be at least
twice the thickness of the plate, with a minimum of I'. Comers should be rounded
to a radius not less than the thickness of the plate, with a minimum of i'. The distance
from the edge of the slut to the edge of the slutted plate should be not less than twice
the thickness of the plate (L-C.C. § 3B).
(xi) In order to minimise costs of handling in the fabricating shop, holes for
erection purposes should, whenever possible, be in the connections (cleats, gussets, etc.),
not in the main members,
STRESS CALCULATfON
The direct stress in fillet and butt welds stressed in tension, compression, or shear.
may be computed by the formula f = P/A where P is the load transmitted by the
connection, and A is the effective sectional area of the weld. The l>cndmg stress, by the
formula fj *= BM/Z where BM is the Bending Moment transmitted by the connection
and Z the section modulus of the weld. Cases of combined bending and direct stress
should be calculated separately bv these two formulae and combined (LX.C- ^ 30-32);
see pages 242-246.
SYMBOLS
Drawings and specifications should clearly indicate sizes and types of welds
require^l ; only widely recognised symbols should be employed,
DETAILING
The length of each side fillet used in end connections should not be less than the
distance between them. Side fillets may be at the edges of the members, or in slots
or holes (L C.C ( 40. ct B S S 18).
In end connections, a single end fillet should not be used without side fillets. With
two or more end fillets, the ends should be turned at least I' to form side fillets ; in
calculating the strength of the connection, if the short return welds are disr^ardrd
the full Irngth of the end welds may be considered effective (L.C.C. f 41).
Owing to the nature of the welded joint, redistribution of stress takes place less
readily than in riveted joints ; so that welded connections, unless skilfully designed,
may lead to dangerous concentrations of stress. Abrupt changes of contour must be
particularly avoided.
In welded work measurement ihould be taken from the edge of the section,
rather than from gauge lines as u-ith ri\*etod work.

METAL ARC WELDING.— Continued.
STANDARDS OF WORK
(i) The surfaces to be welded, and the adjoining metal for a distance of at least i',
must be cleaned free of rust, scale, paint, grease, mineral oil, and dirt, by wire brush, sand
blast, or other eSective method [L.CC. page 5 (iv) ; B,S.S., 6a]-
(ii) Means must be adopted to minimise distortion of the finished parts, e.g- ^^y
jigs, tack welding, intermittent chain, alternative side, or other elective means
[cf- B,S.S, 6c. L.Ca page 5 (vi)].
(iii) Each bead of weld metal must have the slag removed by light hammering
and wire brushing before the next bead is deposited. Light chipping or peening is
permissible ; hammering is not (B,S.S, Qd, L-CC, page 5 (vii)).
(iv) The weld must show a good clean contour ; and on a cut specimen, good fusion
with the parent metal. If the weld metal tends to fold over on the parent metal
without proper penetration, or shows porosity or slag inclusions, it must be cut out
and re welded-
(v) Undercutting must be avoided ; if it occurs, any reduction of area from this
cause must be made good by an additional run [B.S.S. 6d, L.C.C page 5 (vii)],
(vi) Vertical or overhead welding is to be avoided when possible.
(vii) The current used must be within the range defined by the electrode
manufacturer [B,S-S. 6f. L.C.C. page 5 (vii)].
(viii) Before applying paint to welded joints, they should be carefully chipped or
wire-brushed ; it may also be advisable to neutralise the slag remains, if alkaline or
acid (as they may be. according to the grade of electrode employed).

WELD GROUP WITH ECCENTRIC LOAD
PARALLEL TO ITS PLANE
TT^-TT
B
S
R • <l p*T a
In tliis typical example, the weld group sccuriiif^ lliv bracket to the column
has eccentric loading It acting with a leveraKt^ perpendicular to the plane of
the weW group. It must be designed to take the resultant R of the combined
shear and bending stresses, and R should not exceed the allowable shear stress,
say 5 tons per scj, inch. If the throat thickness is t, then : —

... the Benduig stress » = ^^ = ^^^, ^ ^.jjj-
The combined stress K \/r' + B*.
For the purfwses of cdkaUtion, the procedure is to take t in the first instanc*^
as 1' throughout. The value of J< thus ascertained for a throat thickness of l"
is obviously also the combined stress or load per linear inch, whence the required
size of weld can be ascertained from the safe load tabic on page 239.

WELD GROUP WITH ECCENTRIC LOAD

R = Vl-OS* H- -325* - 113
The combined stress or load per linear inch is accordingly 1-27 tons ; and from
the table on page 239, we see that 5/16" iUk-ts are sufficient, or very nearly so.
(Since the combined stress is not to exceed 5 tons per square inch, we take the
safe load given for side welds, viz. 1-10 tons per linear inch.)

EXPLANATrON OF TABLE.
The above table gives the properties of plate girders of the tliree types Uluslrattd, via. : —
(i) without flange plates, (iij with one flange plate, {i\\) with twofltuigc plates, on each flange, respectively.
The properties tabulated are for 14' Hange plates of various tliidonesses (X).
For plates other than 14' wide, the variations in weight and modulus can
be ascertained by using the figures headed J' piaU width.
WEIGHTS AND RIVETS. 3 4' rivets at 4' pitch are assumed (see figure),
t.e,, 3U or I- beads per foot run» with or without flange plates respectively.
STIFFENERS. These are not included in the weights. For notes, see
SECTION MODULI. These are nt-tt, deductions having been made for three or on*- holes in each 0ange,
Willi or viilhout flange plates respectively, i/U' more metaj than the diameter of the rivet being
assumed out of ai:tion.
The following relation is useful for all symmetrically plated sections : —
7 ft*- Tiquired arra oj the plates on each fiance equah the difference between (I) the required S€Cti09% modulus -s-
ongtnal depth, and (ii) original section modulus -^ final depth.
The values taken for areas and moduli must, of course, be the nett values after deducting for rivet holes,
RIVET SHEAR FACTOR, PJTCH OF RIVETS, ETC. The number of rivets per foot run in each flange
required to connect the web to tlie flange angk-s is found by multiplying the vertic^ shear in tons by the
tabulated factor. For derivation, see page GO. ^2,
This method gives a greater pitch than tliat given by the common but less eiatt formula : vertical
shear X pitch = shear or bearing value of one rivet ■ vertical distaiice between the rivets. When the
rivets have to carr>" a superimposed load in addition to coping with the bori2ontal shear, the number of
rivets required will be the square root of the sum of the squares of (ij the number required by the last
paragraphp and (ii) tlic number required for the load.
The pilch so obtained should not exceed in the compre^iun flange 10 limes the thickness of the thinnest
metal.
STOPPING OFF OF PLATES. Having found the required section, the section modulus with one plate
kss can be ascertained from the table, and the position of the point in the yirder where the btudiiig
moment divided by the working stress equals this reduced value, found graphically or by calculation on
the principles described on page 49. It is usual to extend the plates 2 or 3 pitches beyond the
theoretical points.
BROAD FLANGE BEAMS. QREY PROCESS- Many of the built up girders tabulated above Can be
replaced mth advantage by a plain Broad Flange Beam ; see Sununarj' of Sections, page 43.

COMPARISON OF TESTS FOR STRUCTURAL STEEL
Below are given the raain provisions governing the quality of structural steel, as
prescribwl by the British Standards Institution and the principal foreign authorities. The
comparison is both interesting and instructive.
The abbreviations employed are : T = Tensile strength ; / = thickness of test piece.
For Cold Bend tests, the figures given below in terms of t are the diameter of the mandril
round which the test piece must bend through an angle of 180° without sign of fracture.
Approximate equivalents in tons per square inch are given for the specified minimum
tensile ; for more exact equivalents, refer to the table on page 272.
The stated elongations are measured on a gauge length of 200 mm, or 8 inches.

Process. The customary British and American stipulations in regard to process and
chemical analysis are likewise traceable to a variety of consideratioos, not wholly technical.
AmoDg British and American engineers, there is a very strong prejudice against the
Bessemer, and more particularly the Bessemer Basic process. It is attributable to a variety
of considerations — failures in the early days, notably that of the Embabeh Bridge in Egypt;
a desire to exclude foreign steel, which was often of inferior quality ; and, finally, because the
steel maker can, undoubtedly, exercise greater control over the steel in the Open-Hearth Furnace.
Under modem conditions these considerations have lost most of their validity- The
Bessemer Basic process, as employed by the leading Continental works, has been enormously
improved, and the necessity of control during the steel-making process has been minimised by
the use of ores of uniform composition and large mixers.
Chemical Analysis. As is well known, sulphur and phosphorus render steel brittle in tbc
hot and cold states respectively. One common objection to the Bessemer Basic process is that
It demands a higher allowance of phosphorus than the Open-Hearth process, for there is the
risk of burning the metal if the blow is continued utitil the whole of the phosphorus is removed ;
some ifi inevitably added also from the slag when the " additions " — ferro-manganese etc, —
are madtv
In fact, however, the presence of phosphorus up to '08%, in mild steel, seems to be
practically negligible in its effects. Defective steel is most often caused by factors independent
of its chemical composition and of the steel-making process, such as oxidisation, occluded gas,
teeming of the ingots at too high or too low a temperature, insufficient cropping of the ingot.
A defective product may also result from internal stresses caused by iJl-designed rolls, too low
a temperature in rolling, or too rapid cooling.
In short, the Continental practice of prescribing mechanical tests alone {tensile and cold-
bending tests), leaving the manufacturer free to choose his own means of arriving at the desired
results, seems to be the more scientific attitude.
The following pronouncement of the Chairman (Dr. W, H, Hatfield) of a Joint Committee
of the Iron & Steel Institute and National Federation of Iron & Steei Manufacturers on
the Heterogeneity of Steel Ingots is of interest in this connection ; —
" The nature of the inside of the ingot determined the application of the steel to a given
purpose : and the nature of the inside of the steel was entirely independent of the process. The
process used was determined by the cost of that process under local conditions/' (Iron &
Steel Institute. 4th Report on the Heterogeneity of Steel Ingots, 1932. page 222.)*

Thesteel-raakingprocessemployedatDifferdangeisthe Bessemer Basic or Thomas
process. Their beams have been extensively employed in every tj'pe of structure
during the last 35 years : not only in buildings of all kinds, but in crane runways, coaling
staiths. wharves and main-line railway bridges. Many authorities who ordinarily
reject Bessemer Basic steel for bridge construction — e.g., the various Australian
State Railways, the Chinese Government Railways, and the leading Argentine railways
— have made an exception in favour of the Difierdange product, recognising that it is
fully equal to that of the best Open-Hearth steelmakers. Its unimpeachable quality
is due to the facts that the DiSerdange Works make their steel from local ores of
uniform composition, use large muters, and crop the ingot drastically in its passage both
from the blooming to the intermediate mill and from this to the finishing mill ; also to
the nature of the rolling process, i.e.. the Grey Process (see pages U-13).
AVAILABLE QUALITIES.
(N.B. — The undermentioned extras, some only approximate, were those ruling in
Dec. 1947 ; they are liable to alteration without notice.]
(i) • Standard ' quality, tensile strength 26/30 tons per square inch, with
22% minimum elongation in 8 inches (on metal |" and thickert)...nQ extra.
This grade is recommended as the best for most purposes. J
(ii) British Standard quality, tensile strength 28/33 tons per square inch,
with 20?; minimum elongation in 8 inches (on metal J" and thicker|)...6/- per ton
extra, in addition to the undermentioned extra for test certificate or inspection, when
required.
(iii) Soft steel, having a tensile strength of 23i to 28 tons per square inch, with
25% minimum elongation in 8 inches (on metal J" and thickert)...no extra.
(iv) To the German St. 48 specification, viz. : — Tensile strength 48-58 kilos
(SOi tons min.), yield point 29 kilos (18J tons) min., elongation I8^i minimum
in 8 inches.. .about 50/- per ton extra.
(v) To the German St. 52 specification [Chrome- copper steelj, viz. : — Tensile
strength 52-62 kilos (33 tons min,), yield point 36 kilos (23 tons min.), elongation
20% minimum in 8 inches.. .about £3 per ton extra.
(vi) To the mechanical tests of the A.S.T.M. specifications A7 or A9 (tensile
55.000-65,000 pounds). ..no extra.
t British StaDd.-^rd Spedficatiou 15 reduces the minimum elongation to 16% for a thickne^ of
under \' down to {', and eitminates tensile tests on material under i'.
} Compare with the general notes on teasile strength above. The same grade (26/30 tons tensile)
is employed by the Admiralty tor mild steel, and by the Boaid of Trade and I.loyds Registry for boiler
plates. As the modului of ilailieity is practically constant for all grades of mild steel, the difieetiot*
under a given load is the same whether the tensile strength be 26 or 33 tons per square inch. But an
equally reliable product can be given to British Standard tests (28/33 tons tcnsiJe), if preferred.

EXTRA FOR TESTS AND INSPECTION.
For any of the above-mentioned grades there is a further extra when sold subject
to test certificate ur inspection, viz., 4s. Od. or lOa, Od. per ton respectively*
COPPER CONTENT.
Any of the foregoing grades can be supplied with a Copper content, if desired
(' 25 to "35% unless othenvise specified) at an extra of about 15s. Od. per ton.
LONDON BUILDINGS.
The London County Council's 1932 Code of Practice, by stipulating that steel be
made by the Open-Hearth process, temporarily stopped the use of Broad Flange Beams
in London huiidinf;s, The Code is now obsolete, and permission can be obtained
for the use of Broad Flange Beams (in Bessemer Basic steel) by application under §9
of the London Building Act (Amendment Act) 1935 ; i.e., by a procedure similar to
that necessar\- for welded steelwork and other t\"pes of construction not covered by the
Council's Bye'La\\5. *
ROLLING MARGINS-
The roIHng niaryin required on Broad Flange Beams is 4% under and over
theoretical weights ; and appropriate tolerances for wear and tear of rolls, etc., in
profile and dimensions*
\Vith the DiR (maximum) weights — and sections intermediate between the Din
and DiR weights — the rolling margin required is 6% under and over, with tolerances
of 1/16" and 1/8' in the thickness of webs and flanges respectively.
1 Every ajiplicitioD muM be accompanied by adequate p&rticularsaad approval will be subject to
conditions prescribed by the Council in each case.

(Atid or Basic) and the Bessemer Acid Process ; with "OC^^ max. of Sulphur and of Phosphorus.
[Until 1930, a "B" grade — Bessemer Acid or Basic — with -08% Phosphorus was
recognised. Now that British makers |o£ structural steeli all employ the Open-Hearth Process
there is, from the jiiaker$' standpoint, no need to recognise any other process ]

TENSILE TEST PIECES.
BRITISH STANDARD FORMS AND DIMENSIONS.
B.S.S. IS — 1938 Standardizes various test pieces for " Tensile Testing of
Metals."
The A types are chiefly for Plates, Flats, and Sections ; B for unmachincd
Rods and Bars,
TYPE A, This is a flat test piece with enlarged ends ; overall length about IS"*,
parallel length 9" minimum, gauge length 8"; width 2" maximum for
thicknesses of j" to |*, 1^ maximum for material over l".
For thicknesses up to J*, gauge lengths of either 2" or 4", and widths of
I" and 1" respectively are substituted.
TYPE A1. This is an optional alternative for "special sheet and strip
materials"; overall length about 15", gauge length 8", parallel length 9",
width l\
TYPE B. This is chiefly for rods and bars up to 1" diameter: gauge length
8 diameters, distance between grips 9 diameters minimum. {With hexagons and
squares, for " diameter '' substitute distance between the flats.)
TYPE B1. For rods and bars over 1" diameter, the gauge length is 4 diameters,
and the distance between grips is 4J diameters minimum,
N-B, — It must be borne in mind that tensile tests on material as rolled
involve expensive machining and a substantial amount of waste : in the case
of a heavy section, li feet of waste. For this reason, test certificates are
nowadays usually founded on tests made on a specimen taken from the ladle,
and an extra is charged for testing the material as rolled. Sections are tested
in the direction of rolling ; plates both lengthwise and crosswise, or crosswise
only. Except for high-class boiler plates, a reduced elongation is usually allowed
in crosswise tests.

STRUCTURAL STEELWORK,
NOTES ON SPECtFYING.
The particulars which should accompany an enquiry or contract for finished steelwork
may be classed under the following heads : —
(i) Schedule of Material or Bill of Quantities.
(ii) Drawings,
• (iii) Conditions as to quaUty of materials, workmanship, etc,
(iv) Contract conditions special to the contract in question, such as ; — Time for Delivery
(and Erection), Penalty for late Delivery. Place of and Facilities for Delivery, Terms
of Payment, Date for receipt of Tender, Inspection, etc.
BILL OF QUANTITIES,
(i) The most useful form is a list of the various members, each item being so described
as to shew- the whole of the workmanship required thereon. A common form, giving only the
aggregate quantities of cleats, holes and rivets, is difficult to price and almost useless for
estimatmg pui^poses.
(ii) In any cage, it is rarely possible to give a reliable estimate on a Bill of Quantities
alone ; drawings also should be supplied.
I
DRAWINGS.
When competitive tenders are required, drawings should be fully detailed; to leave
either scantlings or connections to the discretion of competing firms, offers an obv*ous induce-
ment to cut down weight and cost to the danger point.
TIME FOR DELIVERY.
Whenever possible the buyer should indicate the time within which delivery is required,
as this greatly affects the cost of materials. Thus, in the case of a very urgent order, the
specification should call for delivery from stock materials.
DATE FOR RECEIPT OF TENDER,
For the steelwork of an average building, a week to a fortnight should be allowed for
receipt of tenders. If time be an important consideration, it is the more necessary that
contractors should have the opportunity of making special enxjuines from roUing mills before
framing their estimates,
SPECIFICATION,
The following conditioas relating to quality of work and materials, tests, inspection, etc,
accord with first-class practice. They are only intended to serve as a draft, some conditions
being omitted and others modified to suit the special circumstances of the case.

STRUCTURAL STEELWORK,
DRAFT SPECIFICATION.
1. QUALITY OF STEEL.
If the steel is intended to be of British manufacture, the usual clause will be, " \Miere
not otherwise specified, all steel to conform to British Standard Specification No. J5 (IS,,.)-"
For Broad Flange Beams, specify that they are to be rrianufactured by the Grev Process.
To this, either add " to the mechanical tests of British Standard Specification 15." or specify
the required grade fsee page 267). It should also be expressly specified that Bessemer Basic
steel may be supplied if of Differdange make.
2. WROUGHT IR0r4.
\\ rought Iron to comply with British Standard Specification for Wrought Iron Xo, 51 ;
Grade C for plates and bars. Grade B for rivets,
3. STEEL CASTINGS.
All steel castings must be thoroughly annealed and after annealing shall shew a tensile
strength of 26 to 35 tons per square inch with a minimum elongation of 15% in 2'. Test
pieces 1" square, after being annealed with the casting, to bend COld without fracture through
an angle 90** round a bar 1' in diameter.
N,B,— For steel castings for marine purposes, see British Standard Specification Xo. 30
1907.
4. CAST IRON,
Cast iron for bearing plates and other parts liable to strain to be of a quality such that a
bar of iron cast from the same melt 3' 6' Icng, 2" deep and 1' wide when supported on bearings
3' 0' apart shall carr>' at the centre without breaking a weight of 2S* cwts., and shall shew a
minimum deflection of J",
6. MALLEABLE CASTINGS.
Malleable castings to be of an approved mixture of iron shewing a tensile strength of not
less than 15 tons per square inch. Samples from each cast to be furnished for tensile and
bending tests,
6. ROLLED MATERIAL.
ilust be free from seams, flaws, cracks, laminations and injurious defects of any kind.
Sections must be rolled as accurately as practicable to the specified weights and
dimensions.
AVhen the specified dimensions are those of a British Standard section, the remaining
dimensions shall be those of the British Standard section thus iiidicatedt. The dimensions
of Broad Manf^e Beams to be as published by R. A, Skelton & Co. Steel & Engmeermg, Ltd.,
London,
7. TESTING AND INSPECTION.
[The spccitication will state whether material wUl be inspected by the engineer's
representative or whether the manufacturer's test certificate will be accepted insstead.
Material must be tested at the rolling mills.
Material supplied from stock cannot be tested nor, as a rule, can the cast be identiBed so
as to enable a test certificate to be furnished. It is necrssar>', however, to allow triflin)^
quantities of bolts and rivets, or materials for making them, to be taken from stock. The
same remark applies to unimportant packings, fishplates, gusset plates and brackets.]

8. ROLLING MARGIN.
For British Sta.ndard sections^ see page 269,
N.B. — For Broad Flange Bpams, Grey Process, the rolling margins required are 4% under
and ovcT theoretical weights (ii**/^ for the maximum, weights) and appropriate tolerances in
profile and dimenstoils ; on aggregate weights a rolling margin of 2\^'i^ can he specified,
excepting the " Uir " weights, however-
&. PLANING, MACHINING, ETC.
All ends of Hcains used as stanchions are to be machined true and square in a fraiztn^ or
ending; machine. All abutting surfaces are to be finished smooth and square, and if necessary,
machined for this purpose after the end ftttm^s have been riveted on.
Flange Plates, it made from sheared plates, must have had at least 1/8' removed OB e*ch
sheared edge by planing.
10. STRAIGHTENING.
Cold straightening of sections must be by pressure and not by hammering.
11. HOLES FOR BOLTS AND RIVETS,
(i) Ordinary round boles are to be of a diameter I, 16' larger than the specified diameter
of bolt or rivet.
(ii) Where not othenvise stated, holes must be drilled, or else punched 1/8* small and
afterwards drilled or reamed (but not drifted) to the required si^e. All burrs due to punching
or dniling must be removed.*
(iii) Alt holes for site connections must be accurately centred ^o as to render reaming ur
drifting during erection unnecessary.
(iv) Multiple members, such as flange plates, to be drilled as far as practicable in one
operation.
12. RIVETS.
N.B. — If the steel contractor has not to erect, state whether site connections will be
riveted or bolted.
(i) Unless otherwise stated, rivets to tje of soft steel, of the quality and to the tests
prescrit>ed for rivets in British Standard Specification No. 15 (page 269 hereof).
(ii) Ordinary rivets to have cup heads formed from a length of shank equal to not less
than 1| diameters. Kivets on bearing surfaces to be Hush countersunk.
(iii) All rivets are to be machine-driven as far as practicable and must completely fill the
holes when closed. If loose or if the heads are badly furnied, cracked, or eccentric to the shank,
or do not bear truly on the plate or bar, such rivets shall be cut out and replaced.

LONDON COUNTY COUNCIL BYE-LAWS, 1937
and
BRITISH STANDARD SPECIFICATION 449—1937
The following pages give a summan,- of the main provisions of Britisli
Standard Specification 449-1937. with references in brackets to the correspond-
ing sections in the L.C.C. Bye-laws (1937). The original specifications must be
referred to for the official text, but this summary will be found useful as a
precis and index.
So far as the steelwork designer is concerned, the two specifications are
ver>- similar in substance; but by section 9 of the 1935 .\mendiTient Act
the Council has powers of modification and waiver. This verj-* important
provision enables the Council to depart from British Standard Specifications
where such departure is necessary' to enable the use of new methods of
construction.
For overseas work it must not be forgotten that these specifications only
purport to lay down minimum requirements for buildings, of normal type
and in Great Britain. In other countries it may be necessary to provide for
greater wind load, and a higher factor of safety in order to allow for lack of
skilled labour in erection, etc.
Again, where foreign materials are to be used, or their use is not to be
excluded, it must be remembered that the British Standard Specifications
represent British manufacturing practice, and may have to be modified
accordingly.
WELDING. B.S.S.449-1937statesthat welding may be used subject to municipal
regulations and bye-laws and to the requirements of B.S.S. 538 for Metal Arc
^Velding and 693 for Oxy-acetylene welding.
The London County Council has published a statement (December, 1937)
indicating the conditions (maximum stresses, methods of calculation, etc.) which
should be observed when applying for permission to use welded steelwork.
The principal technical conditions will be found in the chapter on Welding (pages
234^241).

The stresses in g 10 may be increased by 50% (33J% for high tensile jsteel) if completely
embedded — with at least 4" cover above and on sides — in an approved concrete,* solidly
tamped, and the beams spaced at least 3 inches apart.
12. FJLLER BEAMS (L.C.C. §§ 83, 84).
These, if entirely encased in concrete, may be calculated as composite beams and stressed
to 9 tons per square inch (see table of Resistance Moments, page 229), or 12 tons for high
tensile steel The maximum spacing without suitable reinforcement to be six times the slab
thickness.
Alternatively, the extreme fibre stress, calculated on the filler joists alone, may be increased
to 9 + Mor 13 -f IJ Mor high tensile steel) where / equals thickness of concrete above the top
flange ; but / must not be taken as more than a. The span must not exceed 32 times the
effective depth-
13. OTHER ENCASED BEAMS (L.C.C. §§ G8, 81),
In beams \\jih rectan^Iar concrete encasement (other than filler and grillage beams) the
stress, calculated as plain steel, may t>e increased to SJ tons per square inch (12J tons for
high tensile steel) where (i) the minimum width of $qiid casing is 4" greater than the flange
width of the beam, (ii) the beam is laterally supported by a concrete slab without adjacent Open-
ings, and (iii) the upper surface of the steel beam is at least I J" below and 2}' above the upper
and lower surfaces respectively of the slab.
H. DEFLECTION AND MAXIMUM SPANS (L.C.C. § 84).
The span must not exceed 2i times |16 times for high tensile steel) the depth of a beam,
unless the calculated deflection is less than 1 325lh of the span ; except with filler beams
§ 12 above.
15- COLUMN STRESSES (L.CX. § 83a).
The ratio / g is limited to 150 in main members. 240 in subsidiary members (200 in L.C.C,
§ 85), This section spei-ifies the allowable stresses. These are tabulated on page 95, with inter-
mediate values obtained, as directed, by interpolation,
16 EFPECTIVC LENGTH OF COLUMN (L,C,C. §§ 86 tO 90).
For dctemiinmg axial stress, the efl^ective length is to be computed as follows : —
{a) Both ends held in position and restrained in direction. 0-7 of the actual lenffth.
(&) Both ends held in position and one end restrained in direction, 0-85 of the actual
length.'
{c) Both ends held in position, but unrestrained in direction, the actual length "

resistance moment of the restraining menxber(s] and connection(s) equa^ls : —
(i) 0*25 of the resistance moment of the column section calculated ai^ a beam with an
extreme fibre stress oi 8 tons per sq. inch"- for ^ g ratios up to 120^
(ii) 0-25 + 0'02 {l/g—120) of the resistance moment of the compression member for
values of l/g exceeding 120, where I = efiective length and g = radius of g^Tation about the
axis under consideration.
For a column to be considered continuous through a spliced joint, the moment of resistance
at the cross section of the splice must comply with the foregoing limits in such a case, a
column may be considered to be "" restrained in direction " if the resistance moment of the
supporting member is not less than one-half of the above-mentioned limits.
A column having a flat or sqttare end fixed in position' can be assumed— for the purpose
of computing its effective length — to have an end connection with a resistance moment equal
to one-fourth of its own. It can be considered efEectivelv " restrained " (as regards crippling due
to axial load) if its length is not over 120 //g, otherwise only partially restrained,
17. ECCENTRIC LOADING ON COLUMNS (LC.C, §§ 87 to 90).
(i) The calculated maximum stress may exceed the ordinary worlting stress of § 1 5 according
to a formula given. If W - actual load, then Fc ^ W/a ; and if F, is the ordinary working
stress of § 15. the increased stress allowable is determined bv the ratio Fc Fy L.g., H l/g =
96, Fi = 4 ; so that, if Fc = 2, Fc F, = 60%. Then, by "the formula |or, in practice, from
the charts given in the appendix) it win be seen that the maximum compressive stress may be
taken as 5 instead of the normal 4 tons per sq inch,
(ii) Bending Moment induced by a beam may be regarded as divided between the column
lengths above and below the beam in proportion to their stiffness {l/l), " account being taken
of all bending or shearing forces at any joint,"
(iii) Bending Moments due to eccentric loading at a given floor level may be disregarded at
other levels if the column is " effectively restrained in relation to the eccentric load " at the
adjacent floor levels.
I8.t STRESSES DUE TO WIND {L.C.C § 90)-
The normal working stresses given in §§ 10, 13, 15, 17 (including stresses in roof trusses,
purlins, and their connections! may be increased by one-third where the increased stress is
induced solely by wind pressure.
PART VL DETAILS OF CONSTRUCTION,
19, MINIMUM THICKNESS OF STEEL, (L,C.C. §§ 80 and 30G).
The minimum thickness allowed is 5/16' in external, J* in internal construction These
limits are not applicable to light work (defined), nor to rolled sections or packings. The webs
and flanges of built-up columns must not be under |' thick (5/16* for H.T. steely.
20/22. EFFECTIVE SPAN, OEPTH AND SECTIONAL AREA-
Span is defined in § 20. By § 21, the effective depth of a plate girder is to be talcen as the
distance between the centres of gravity of the flanges, or the depth over the angles, whichever
is the less.
By § 22, the nett sectional area is to be taken for tension members ; and for compression
members if subject also to tension. Shear stress is to be calculated on the depth of the web
plate in a plate girder ; on the full depth of the section in a rolled steel beam or channel.

23- PLATE GIRDERS
Tliis seciiLsn gi\'es detailed provisions for the design of plate girders, including the
provision of intermediate stiffeners ^vhene\ er the unsupported depth of the web plate is more
than CO limes its thickness.
24, SOLID ROUND COLUMNS (L.C.C. §73).
Theae are to have machined shouldered ends to receive the caps and bases, which are to !>e
shrunk or screwed on before machining the bearing surfaces. The length or diameter of the
cap or baseplate is not to he ]?ss than 1 J (d + 3), where d is the diameter of the reduced end.
A formula is given for determining the minimum thickness of the caps and bases, giving results
ranging from k d for light columns to d for heavy columns. «
25. STANCHION CAPS AND BASES (LX-C. §§ 69 tO 72). '
The prescriptions for caps and bases other than those for solid rounds include the following :
(i) The rivets in bases need only be capable of transmitting 60% of the axial load,
(ii) Stanchion bases must t>e machined after riveting up complete. But machining can
be dispensed with if rivets and gussets are designed to transmit the whole load,
(iii) A formula for computing the thickness of slab bases (§ 28a).
26 LATTICE MEMBERS.
This section contains prescriptions governing the design of latticed columns, of columns
joined by batten plates, and of tension members with intermediate tie plates.
27. RIVETS (LC.C. §§77 to 79).
This section prescribes the minimum and maximum pitch of rivets, minimum distances
from edge of plate, etc The effective diameter of a rivet mav be Uken to be that of the
finished rivet, x.e,, the diameter of the rivet hole.
PART VII. FABRICATION AND ERECTION.
28. PREVENTION QF CORROSION.
This is referred to bnetiy in general lerm^s. Protection from corrosion is largely secured
by the provisions for protection against fire [BS.S. 476 ; L.C.C. fS 66 to 68).
29. FABRICATION (L.C.C. §§ 7-1 to 7fi).
This is to l>e done in the shops as far as possible. Black bolts may be used in site connections
only if »»uitablc dead bearings are provided to resist all shear forces involved (but dead bearings
arc not required for rool trusses or secondary floor beams), "Washers are to be used under all
nuts, and on tapered surfaces washers must l>e used under bolt heads also. § 29c prescribes that
any welding must conform with Hniish Standard Specification 538 for arc-wclding, fion for
gas-veldm){.

1. GREY PROCESS.
These beams should be specified as " Broad Flange Beams, Grey Process."
2. SIZES.
The " nominal " sizes of Broad Flange Beams. Grey Process, are only approximate.
exact dimensions are given in the various tables under the heading " Exact Sizes";
are subject of course to the customary rol lOfj margins or tolerances (see page 2G8).
The

always straightened (when necessary) free of charge before
iceptional precision is required, "double straightening " is
5. CUTTING TO LENGTHS.
Beams are cut to lengths^ by hot-saw or otherwise, within 4* over, without extra charge.
6. EXACT LENGTHS AND SQUARE ENDS,
Beams can be cut to " exact " lengths, both ends square, within a margin of 1/8' under
and over, at the following extras- (II the margin is to be taken one way only, it must
be increased to 1/4') : —
Sections up to S' deep 12s. Od. per length.

[The treatment is to hot-saw only a little over the specified lengths, and then to mill the
ends at the fraising machine down to the " exact " lengths. Consequently, unltrss the required
finished lengths are known before rolling^ additional labour, and a corresponding extra charge,
may be incurred.]
If it will suffice for one end to be squared, and a margin in length of 1/4' under and over
measured along the axis of the beam can be allowed, the above-mentioned extras will be
reduced by 50%, This procedure is not suitable if the beams are to be drilled at both ends.
Special extras are charged for bevet cuts.
N.B. — In the case of the DiR Sections (Maximum weights), the extras for "exact"
lengths are determined by the actual depth of the section.
7- MINIMUM AND MAXIMUM LENGTHS.
All sections can be rolled in lengths up to 100 feet or more. Lengths under 10 feet or
over 49 (eel are charged extra. Pieces over 30 feet or weighing over 2 tons usually incur
freight extras. Very heavy pieces are also liable to extras for cranage at port of shipment.

15- TIME REQUIRED FOR DELIVERY.
In the various tables of sizes and safe Joads, each section is marked with a UUer indicating
the time required for deliverv (in normal times) ; these symbols are to be interpreted as
follows : —

These indi^-ations are only intended to gi\c an approximate idea of the time required for
deliver^-, which will vary according to the state of trade, and tonnage required. Thus, rolii
can usually be mounted spec%aiiy lor lots of 100 tons or more of a single section ; so that,
as the capacity of the Mill is 500 to 1,000 tons per day. large Orders can often be rolled at very
short notice. The smaller quantities normally specified can only be rolled as the rolls go in (or
the various sections ; except that small lots of most sizes can usually be supplied from stock
at mills — in " Stock " quality, i.e., mild steel of good qualitj- not sold to specific testa.
To the time required lor rolUng, a further allowance must he made for carriage from mills
to destination ; this averages two weeks to all parts of the United Kinj^dom. Time must
also be allowed for any painting, drilling, or other Morkmanshjp required.
